Description

Technical Field

[0001] This invention relates to the field of rapid drying equipment technology, and in particular to a rapid drying and puffing device for microbial fertilizers. Background Technology

[0002] The rapid drying and puffing device for microbial fertilizers is mainly used for the drying and puffing process of microbial fertilizers. This device rapidly evaporates moisture by combining hot air and steam, reducing the moisture content of the microbial fertilizer to a level suitable for storage and use in a short time, while maintaining its microbial activity. The puffing process increases the porosity of the particles through high temperature and rapid expansion, giving them better air permeability and a longer shelf life.

[0003] This device is usually equipped with a temperature control system that can precisely regulate the drying temperature to avoid killing microorganisms with high temperatures. Through this technology, microbial fertilizers can not only improve fertilizer efficiency, but also enhance their stability and activity in the soil, which helps plant growth. The expanded fertilizer granules are usually uniform in shape and moderate in density, making them easy to apply and store for a long time.

[0004] Chinese Patent Publication No. CN212924833U discloses a rapid drying and puffing device for microbial fertilizer, including a base, a support plate fixedly connected to the upper end of the base, a conveyor platform fixedly connected to the upper end of the support plate, a drying and puffing box connected to the output end of the conveyor platform, and a mixing box connected to the lower end of the drying and puffing box via a corrugated pipe. One end of the mixing box is hinged to the side wall of the support plate via a hinge seat. The upper end of the base is connected to the lower end of the mixing box via a reciprocating shaking mechanism. The reciprocating shaking mechanism includes a drive groove, which is opened in a horizontal straight line at the upper end of the base. A bearing is embedded in the groove wall at the end of the drive groove away from the support plate. This patent document allows the mixing box to shake and agitate simultaneously while stirring the dried and puffed microbial fertilizer, improving the stirring effect and increasing the production efficiency of the microbial fertilizer.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Example 1, as Figure 1 , Figure 2 and Figure 3 As shown, a rapid drying and puffing device for microbial fertilizer includes three ring-shaped support frames 1. The upper ends of the three support frames 1 are all fixedly connected to mounting rings 2. A drying cylinder 3 is fixedly connected to the inner surface of the mounting rings 2. A cylinder top 4 is fixedly connected to the upper end of the drying cylinder 3. An inlet pipe 5 is fixedly connected to the rear side of the middle of the upper end of the cylinder top 4. The lower end of the inlet pipe 5 communicates with the inner cavity of the cylinder top 4. A shell 6 is fixedly connected to the middle of the upper end of the support frames 1. A motor 7 is fixedly connected to the bottom wall of the shell 6. A cleaning and stirring assembly 8 is fixedly installed at the lower end of the drying cylinder 3. Through the cleaning and stirring assembly 8, residual microbial fertilizer on the inner wall of the device can be scraped off during operation. Simultaneously, the cleaning and stirring assembly 8 continuously strikes the impact block 9 during use, causing the device to vibrate and shake off residual microbial fertilizer from the surface. Therefore, through the cleaning and stirring assembly 8, the inner surface of the device remains clean during operation, preventing the accumulation or adhesion of microbial fertilizer on the device surface over a long period, which would affect the subsequent drying effect.

[0036] The drive component 86 and the scraping component 87 work together to continuously reciprocate during the processing, scraping off the residue at the top of the device, thereby improving the efficiency of subsequent processing.

[0037] Impact blocks 9 are fixedly connected to the upper front edge and the upper rear edge of the inner surface of the drying cylinder 3, and a heating mechanism is fixedly installed on the outer surface of the drying cylinder 3.

[0038] The heating mechanism described above consists of a hot air heating system and a heat exchanger, as described in the prior art. Its working principle is as follows:

[0039] First, hot air or steam is heated to the required temperature by a heating system and then sent into the inner cavity of the drying cylinder 3 by a fan or other transmission method. Inside the drying cylinder 3, the fertilizer granules come into contact with the hot air and the moisture in them evaporates rapidly. At the same time, due to rapid heating, the fertilizer granules expand and form a granule shape with good air permeability. Furthermore, the heat exchanger improves the heat transfer efficiency by exchanging heat between the hot air and the cold air or cold material, ensuring the uniformity of the heating process and energy-saving effect.

[0040] Therefore, the hot air heating system and heat exchanger mentioned above are conventional designs in the existing technology. Their specific installation methods, circuit connection methods and control methods are also conventional designs, and this solution will not elaborate on them in detail.

[0041] Example 2: Based on Example 1, this example aims to scrape off the residual microbial fertilizer on the inner surface of the drying cylinder 3 during the heating and drying of the microbial fertilizer.

[0042] For details, please refer to Figure 1 , Figure 2 and Figure 3 The cleaning and stirring assembly 8 includes a conical shell 81 fixedly connected to the lower end of the drying cylinder 3. An opening plate 82 is fixedly connected to the lower end of the conical shell 81. A rotating rod 83 is rotatably connected to the middle of the upper end of the opening plate 82. A stirring plate 84 is fixedly connected to the rear of the outer surface of the rotating rod 83. The outer surface of the stirring plate 84 is in contact with the inner surface of the drying cylinder 3 and the conical shell 81. A plurality of rectangular holes 85 penetrating the right end of the stirring plate 84 are linearly arrayed on the left end of the stirring plate 84. A drive assembly 86 is fixedly installed on the upper part of the outer surface of the rotating rod 83. A scraping assembly 87 is fixedly installed on the upper part of the outer surface of the rotating rod 83. The scraping assembly 87 is located on the upper side of the drive assembly 86. The upper end of the rotating rod 83 is fixedly connected to the output end of the motor 7 through a coupling.

[0043] Before processing, the moist microbial fertilizer needs to be added into the feed pipe 5 through the opening, and then the microbial fertilizer falls into the drying cylinder 3;

[0044] As described above, the upper end of the rotating rod 83 is fixedly connected to the output end of the motor 7 via a coupling. Therefore, when the motor 7 is started, its output end can drive the rotating rod 83 to rotate via the coupling. When the rotating rod 83 rotates, since a stirring plate 84 is fixedly connected to its outer surface, and the outer surface of the stirring plate 84 is in contact with the inner surface of the drying cylinder 3 and the conical shell 81, the stirring plate 84 rotates simultaneously with the rotating rod 83. This achieves the effect of stirring the microbial fertilizer while simultaneously allowing the outer surface of the stirring plate 84 to stir the drying cylinder 3 and the conical shell that are in contact with it. The residual microbial fertilizer on the inner surface of 81 is scraped off, and the left end of the stirring plate 84 has a linear array of rectangular holes 85 that penetrate the right end of the stirring plate 84. During the stirring process, the clump of microbial fertilizer can be broken up by the stirring plate 84 and the rectangular holes 85. By breaking up the clump of microbial fertilizer and scraping off the residual microbial fertilizer on the inner wall of the drying cylinder 3 and the conical shell 81, the subsequent heating mechanism can heat and dry the moist microbial fertilizer quickly. The dried microbial fertilizer can fall out from the holes on the surface of the perforated plate 82.

[0045] Example 3: Based on Example 2, this example aims to scrape the microbial fertilizer accumulated on the surface of the device into the drying cylinder 3.

[0046] For details, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 12 The scraping assembly 87 includes a fixed rod 871 fixedly connected to the front and rear sides of the upper part of the outer surface of the rotating rod 83. The ends of the two fixed rods 871 that are far apart from each other are fixedly connected to a conical top ring 872. A fixed block 873 is fixedly connected to the lower rear edge of the outer surface of the cylinder top 4. A blocking block 874 is fixedly connected to the right end of the fixed block 873. A connecting ring 878 is rotatably connected to the upper part of the outer surface of the rotating rod 83. A connecting plate 879 is fixedly connected to the rear part of the outer surface of the connecting ring 878. An arc-shaped block 875 is fixedly connected to the rear end of the connecting plate 879. A guide ring 876 is slidably connected to the inner surfaces of the fixed block 873, the blocking block 874, and the arc-shaped block 875. A spring 877 is fixedly connected to the upper part of the ends of the blocking block 874 and the arc-shaped block 875 that are close to each other. The spring 877 is located outside the guide ring 876. The connecting ring 878 is located between the connecting plate 861 and the fixed rod 871. A limit assembly 80 is fixedly installed at the right rear edge of the inner surface of the drying cylinder 3.

[0047] Furthermore, the two striking components 863 include a C-shaped plate 8631 fixedly connected to the front of the outer surface of the ring 862, a cylinder 8632 fixedly connected to the top wall of the C-shaped plate 8631, a connecting rod 8633 fixedly connected to the inner cavity of the cylinder 8632, a striking block 8634 rotatably connected to the lower end of the cylinder 8632, a mounting hole 8635 opened on the upper end of the striking block 8634 near the cylinder 8632, the lower end of the connecting rod 8633 rotatably connected to the bottom wall of the mounting hole 8635, a torsion spring 8636 fixedly connected to the bottom wall of the mounting hole 8635, and the other end of the torsion spring 8636 fixedly connected to the outer surface of the connecting rod 8633.

[0048] Furthermore, the limiting component 80 includes a mounting plate 801 fixedly connected to the rear right edge of the inner surface of the drying cylinder 3. The upper front part of the mounting plate 801 has a placement groove 802. The inner surface of the placement groove 802 is slidably connected to a top block 803. The lower end of the top block 803 and the end close to the bottom wall of the placement groove 802 are fixedly connected to a spring 804. The lower middle part of the cone-shaped ring 872 has a placement groove 805. The inner surface of the placement groove 805 is slidably connected to a top block 806. The upper end of the top block 806 and the end close to the top wall of the placement groove 805 are fixedly connected to a spring 807.

[0049] Furthermore, a slide rail 8731 extending through the right end is provided on the upper front side of the left end of the fixing block 873, a shaped groove 8732 extending through the right end is provided on the front left end of the fixing block 873, and a slide rail 8733 communicating with the inner cavity of the shaped groove 8732 is provided on the lower front side of the left end of the fixing block 873.

[0050] Preferably, the left end of the blocking block 874 is provided with a second irregular groove 8741 that extends through its right end, the upper front side of the outer surface of the blocking block 874 is provided with an arc-shaped groove 8742 that communicates with the inner cavity of the second irregular groove 8741, the upper left end of the arc-shaped block 875 is provided with a third slide rail 8751 that extends through its right end, the middle left end of the arc-shaped block 875 is provided with a third irregular groove 8752 that extends through its right end, the upper front end of the arc-shaped block 875 is provided with an arc-shaped groove 8753 that communicates with the inner cavity of the third irregular groove 8752, the lower left side of the middle left end of the arc-shaped block 875 is provided with a fourth slide rail 8754 that communicates with the inner cavity of the third irregular groove 8752, the guide ring 876 is located in the inner cavity of the third slide rail 8751 and the first slide rail 8731, and the cone-shaped ring 872 is located in the inner cavity of the third irregular groove 8752, the second irregular groove 8741 and the first irregular groove 8732.

[0051] As described above, the two fixed rods 871 and the four connecting plates 861 are all fixedly connected to the outer surface of the rotating rod 83. Therefore, when the rotating rod 83 rotates, they can all rotate simultaneously. When the conical top ring 872 rotates with the two fixed rods 871, the top block 806 at its lower end is slidably connected to the placement groove 805 opened at the lower end of the conical top ring 872. At the same time, a spring 807 is fixedly connected between the top block 806 and the top wall of the placement groove 805. Therefore, when the top block 806 rotates with the conical top ring 872, the top block 806 can push the arc block 875 to rotate and move around the center point of the conical top ring 872. When the arc block 875 moves, it can gradually squeeze the spring 877. As described above, the guide ring 876 is located in the inner cavity of the slide rail 8751 and the slide rail 8731. Therefore, the guide ring 876 plays a sliding guiding role. The function is as follows: after the spring 877 is compressed to its maximum value, the arc block 875 gradually approaches the blocking block 874. During this process, the top block 803 gradually approaches the top block 806. When the top block 803 passes the lower end of the arc block 875, it will be squeezed by the lower end and contract into the placement groove 802. At the same time, the spring 804 is squeezed and contracted until the top block 803 moves to the upper end of the top block 806. At this time, the top block 803 is no longer squeezed, causing the spring 804 to rebound. This causes the top block 803 to squeeze the top block 806 into the placement groove 805. Then, the cone top ring 872 drives the top block 806 to slide into the irregular groove 8752 and the slide rail 8754. At this time, the top block 806 no longer resists the arc block 875, causing the spring 877 to rebound to the initial state and push the arc block 875 back to the initial position.

[0052] During the process of the arc block 875 returning to its initial position, since it is fixedly connected to the second connecting plate 879, and the connecting ring 878 fixedly connected to the second connecting plate 879 is rotatably connected to the outer surface of the rotating rod 83, the arc block 875 rotates around the center point of the connecting ring 878, thereby causing the second connecting plate 879 to scrape off the microbial fertilizer that fell on the top of the first connecting plate 861.

[0053] When the two fixed rods 871 rotate, in order to avoid affecting the normal operation of the device, this solution provides an arc-shaped groove 8753 at the upper front end of the arc-shaped block 875, which communicates with the inner cavity of the irregular groove 8752. At the same time, an arc-shaped groove 8742 at the upper front end of the blocking block 874 communicates with the inner cavity of the irregular groove 8741. Therefore, when the cone-shaped ring 872 rotates with the two fixed rods 871, the two fixed rods 871 can slide into and out of the arc-shaped groove 8753 and the arc-shaped groove 8742, thereby avoiding affecting the normal operation of the device.

[0054] During the process of the arc-shaped block 875 moving back to its initial position, the cone-shaped ring 872 can continue to drive the top block 806 from the arc-shaped groove 8753 and the slide rail 8733 until it moves back to the right end of the arc-shaped block 875 in its initial position. Then the above operation is repeated to complete the reciprocating scraping effect.

[0055] Example 4: Based on Example 3, this example aims to remove the microbial fertilizer adhering to the inner surface of the device while scraping off the residual microbial fertilizer at the top of the device.

[0056] For details, please refer to Figure 3 , Figure 4 , Figure 8 and Figure 11 The two striking components 863 include a C-shaped plate 8631 fixedly connected to the front of the outer surface of a ring 862, a cylinder 8632 fixedly connected to the top wall of the C-shaped plate 8631, a connecting rod 8633 fixedly connected to the inner cavity of the cylinder 8632, a striking block 8634 rotatably connected to the lower end of the cylinder 8632, a mounting hole 8635 opened on the upper end of the striking block 8634 near the cylinder 8632, the lower end of the connecting rod 8633 rotatably connected to the bottom wall of the mounting hole 8635, a torsion spring 8636 fixedly connected to the bottom wall of the mounting hole 8635, and the other end of the torsion spring 8636 fixedly connected to the outer surface of the connecting rod 8633.

[0057] As described above, both C-shaped plates 8631 are fixedly connected to the outer surface of the ring 862, and the ring 862 is fixedly connected to four connecting plates 861. The four connecting plates 861 are fixedly connected to the outer surface of the rotating rod 83. Therefore, the two C-shaped plates 8631 rotate simultaneously around the center point of the rotating rod 83. When the ring 862 drives the C-shaped plates 8631 on both sides to pass the impact block 9 on the same side, the striking block 8634 on the same side will strike the impact block 9 on the same side, thus generating vibration. When the striking block 8634 on the same side passes the impact block 9 on the same side, it will be squeezed. The plate is pressed down and then folded inward. During the folding process, the torsion spring 8636 on the same side rotates and contracts until the striking block 8634 disengages from the impact block 9 on the same side. At this time, the torsion spring 8636 on the same side is no longer subjected to the force of rotation and contraction, thereby releasing the force of rotation and contraction and causing the striking block 8634 to return to its initial state. Therefore, when the C-shaped plates 8631 on both sides rotate with the ring 862, the striking blocks 8634 on both sides can continuously strike the impact blocks 9 on both sides to generate vibration, shaking off the microbial fertilizer adhering to the inner wall of the device, thereby improving the subsequent drying and puffing effect.

[0058] It should be noted that the specific installation method of the motor 7, the circuit connection method, and the control method used in this invention are all conventional designs, and will not be described in detail here.
