The sterilization tank is equipped with multiple light box slots, and each slot has a light box for sterilization and disinfection. The light box contains a UV tube, and sterilization can be achieved through the light irradiation of the UV tube, which has certain positive significance. However, when the soil falls from the receiving port, some of it may stick together and pile up. When it falls through the sterilization tank, it cannot be fully sterilized. Summary of the Invention

[0004] The purpose of this application is to provide a soil treatment nutrient soil disinfection device to solve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution of this application is as follows:

[0006] A soil disinfection device for soil treatment includes a disinfection chamber and multiple disinfection wheels rotatably disposed within the disinfection chamber.

[0009] Preferably, two adjacent disinfection wheels are spaced apart; the dispersion column has a drying chamber inside, and any one of the drying chambers is connected to a portion of the disinfection chambers on both sides of the disinfection wheel.

[0010] Preferably, there are multiple disinfection chambers, which are arranged vertically.

The drive shafts corresponding to the disinfection wheels in any two adjacent disinfection chambers are meshed with each other by gears, and the connecting ports correspond to each other during the meshing and rotation.

[0011] Preferably, the number of disinfection chambers is two.

[0012] Preferably, a sliding block is provided below the lowest disinfection chamber, the sliding block is reciprocating, and the sliding block is provided with a V-shaped groove that extends vertically through the sliding block.

[0016] The soil treatment nutrient soil sterilization device disclosed in this application involves conveying nutrient soil to the top of the sterilization chamber via a conveyor, such as a conveyor belt. A connecting hole in the sterilization wheel corresponds to the nutrient soil inlet. The nutrient soil on the conveyor belt enters the interior of the sterilization wheel through the nutrient soil inlet and the connecting hole. Under the action of the dispersion column, the nutrient soil is gradually dispersed. Simultaneously, high-temperature steam is introduced through the steam inlets on both sides of the sterilization chamber. The high-temperature steam, also under the action of the dispersion column, fully mixes with the nutrient soil, thereby sterilizing it. Compared to traditional sterilization devices, the nutrient soil can be fully dispersed without the need for an additional energy-driven dispersion mechanism, thus reducing the energy consumption for nutrient soil treatment. Furthermore, the sterilization wheel has a circular internal structure. When steam enters the sterilization wheel, it can diffuse within the cavity of the sterilization wheel. Due to the action of the dispersion column, the steam can be further mixed within the cavity, thus achieving more thorough contact with the nutrient soil and achieving complete sterilization.

[0030] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0031] like Figure 1-8As shown, a soil disinfection device for soil treatment includes a disinfection chamber 100 and a plurality of disinfection wheels 6 rotatably disposed within the disinfection chamber 100. The disinfection wheels 6 have cavities 65 inside, and a plurality of dispersion columns 64 are disposed in the cavities 65. A connecting port 60 is provided on the peripheral wall of the cavity 65. A soil inlet 10 is provided at the top of the disinfection chamber 100, a soil outlet 12 is provided at the bottom, and steam inlets 11 are provided on the left and right sides.

[0032] The disinfection chamber 100 can be the internal area of ​​a shell structure, for example, a plate-like structure enclosing a shell formed by welding.

[0033] The disinfection wheel 6 is preferably a disc-shaped structure that can rotate in the cavity 65. In particular, the rotation of the disinfection wheel 6 can be achieved by a rotating shaft 62, such as the rotating shaft 62 passing through the disinfection cavity 100, and the disinfection wheel 6 is set on the rotating shaft 62. The rotation of the rotating shaft 62 can be achieved by a servo motor 5 or a drive mechanism formed by the combination of servo motor 5 and reducer, such as by setting a specific rotation program through a PLC controller.

[0034] The disinfection wheel 6 has a cavity 65 inside. Preferably, the overall outline of the disinfection wheel 6 is a columnar structure, and the cavity 65 inside it is also a columnar structure.

[0035] Multiple dispersion columns 64 are arranged inside the sterilization wheel 6, with the dispersion columns 64 spaced apart from each other, so that the nutrient soil can be fully dispersed when it flows inside the sterilization wheel 6, thereby ensuring thorough mixing with steam.

[0036] Multiple disinfection wheels 6 are axially spaced on the rotating shaft 62, and the positions of the connecting ports 60 on each disinfection wheel 6 are opposite to each other.

[0037] The nutrient soil inlet 10 at the top of the disinfection chamber 100 is used for feeding, the nutrient soil outlet 12 at the bottom is used for discharging, and the steam inlets 11 on the left and right sides are used to introduce high-temperature steam into the disinfection chamber 100.

[0038] For example, the internal contour of the disinfection chamber 100 matches the volume occupied by the multiple disinfection wheels 6. Specifically, the disinfection chamber 100 is a cylindrical area, and the multiple disinfection wheels 6 also form cylindrical areas. Furthermore, the cylindrical areas formed by the disinfection wheels 6 are as large as possible to the cylindrical areas of the disinfection chamber 100, so as to increase the effective treatment area of ​​the steam on the nutrient soil.

[0039] It should be noted that in some embodiments, when multiple disinfection wheels 6 are arranged axially along the rotation shaft 62, a baffle is provided on the nutrient soil inlet 10 at the top of the disinfection chamber 100. The baffle is located directly above the area between two disinfection wheels 6 to prevent nutrient soil from entering the area outside the disinfection wheels 6.

[0040] The nutrient soil and high-temperature steam both enter through the connecting port 60.

[0041] The nutrient soil is conveyed to the top of the disinfection chamber 100 by a conveyor device, such as a conveyor belt. At this time, a connecting hole in the disinfection wheel 6 corresponds to the nutrient soil inlet 10. The nutrient soil on the conveyor belt enters the interior of the disinfection wheel 6 through the nutrient soil inlet 10 and the connecting hole. Under the action of the dispersion column 64, the nutrient soil is gradually dispersed. At the same time, high-temperature steam is introduced into the steam inlets 11 on the left and right sides of the disinfection chamber 100. The high-temperature steam is also fully mixed with the nutrient soil under the action of the dispersion column 64, thereby completing the sterilization of the nutrient soil. Compared with traditional disinfection devices, the nutrient soil can be fully dispersed without the need for an additional energy-driven dispersion mechanism, thereby reducing the energy consumption for nutrient soil treatment. In addition, the interior of the disinfection wheel 6 is a circular structure. When steam enters the interior of the disinfection wheel 6, it can diffuse in the cavity 65. Due to the action of the dispersion column 64, the steam can be further mixed in the interior of the cavity 65, thereby more fully contacting the nutrient soil and achieving full sterilization.

[0042] In other embodiments, the disinfection wheel 6 is rotatable, and the conveyor belt transporting the nutrient soil can also be intermittently moving. For example, a movement pattern can be formed where: when a connecting port 60 in the disinfection wheel 6 is aligned with the nutrient soil inlet 10, the conveyor belt moves normally. At this time, the nutrient soil enters the interior of the disinfection wheel 6 through the nutrient soil inlet 10 and its corresponding connecting hole. When the nutrient soil is dispersed by the dispersing columns 64, the conveyor belt can stop transporting, while the disinfection wheel 6 can rotate. Throughout the process, steam is continuously introduced. When the disinfection wheel 6 rotates, the nutrient soil that has entered the central part of the area formed by the multiple dispersing columns 64 will move from the center to the edge, thus changing the original falling path of the nutrient soil, increasing its disorder and randomness, thereby further improving the mixing degree with steam to ensure more thorough disinfection. Simultaneously, the intermittent rotation of the disinfection wheel 6 can prevent the accumulation of nutrient soil on the dispersing columns 64, thereby avoiding blockage in the area of ​​the dispersing columns 64.

[0043] In some further embodiments, the dispersed columns 64 are arranged vertically in rows and columns to form a square column group; the number of connecting ports 60 is four, and the four connecting ports 60 are arranged circumferentially at intervals, with the four corner positions of the square column group corresponding to the four connecting ports 60 respectively.

[0044] The vertical arrangement of rows and columns indicates that multiple dispersion columns 64 are arranged in multiple rows and columns, and the extension direction of each row is perpendicular to the extension direction of each column. Furthermore, the number of dispersion columns 64 in each row is the same as the number of dispersion columns 64 in each column.

[0045] Since all the dispersion columns 64 form a square column group, the square column group forms four corner positions. Each corner position corresponds to a dispersion column 64 and a connecting port 60. That is to say, when the nutrient soil enters the sterilization wheel 6 from the connecting port 60, it will pass through the right-angled triangular area formed by multiple dispersion columns 64, and then through the other half of the right-angled triangular area formed by multiple inverted dispersion columns 64, and then be discharged from the nutrient soil outlet 12 at the bottom. In the whole process, the nutrient soil passes through two right-angled triangular areas formed by multiple dispersion columns 64, one upright and one inverted. It should be noted that the first upright right-angled triangular area conforms to the Dalton plate structure, and the other inverted right-angled triangular area also conforms to the Dalton plate structure. Therefore, when the nutrient soil enters the first upright right-angled triangular area, the amount of nutrient soil falling into the center will be larger. When all the nutrient soil enters the inverted right-angled triangular area, the nutrient soil will eventually concentrate and fall from the middle of the bottom of the inverted triangle. The goal is to discharge the nutrient soil directly from the nutrient soil outlet 12 as much as possible. Firstly, the nutrient soil initially falling from the first upright right-angled triangle region follows a normal distribution. When this nutrient soil enters the inverted right-angled triangle region, it still follows a normal distribution. Therefore, a large portion of the falling nutrient soil will ultimately land at the lower center of the inverted right-angled triangle region, i.e., at the nutrient soil outlet 12. Secondly, within the inverted right-angled triangle region, the largest upright right-angled triangle region is the central region. Therefore, even if there are countless upright right-angled triangle regions within the inverted right-angled triangle region, the central region will always have the largest area. Thus, the normally distributed nutrient soil falling from the first upright right-angled triangle region will continue to fall from the inverted right-angled triangle region in a similar normal distribution or central concentration pattern, aiming to land as close as possible to the nutrient soil outlet 12, thereby ensuring efficient discharge.

[0046] In some further embodiments, the number of cavities 65 on the sterilization wheel 6 is two, and the two cavities 65 are located on both sides of the sterilization wheel 6 respectively.

[0047] Two cavities 65 are provided, and the two cavities 65 are separated by a partition 61. The reason for separating the two cavities 65 is twofold: firstly, it provides a location for the dispersing column 64 and the rotating shaft 62; secondly, it strengthens the overall structure of the disinfection wheel 6.

[0048] It should be considered that increasing the number of cavities 65 will also improve the processing efficiency of the nutrient soil.

[0049] In some further embodiments, two adjacent disinfection wheels 6 are spaced apart; the dispersion column 64 is provided with a drying chamber 63, and any drying chamber 63 is connected to a portion of the disinfection chamber 100 on both sides of the disinfection wheel 6.

[0050] Please refer to Figure 9 The dispersion column 64 is a hollow structure, forming an internal drying chamber 63; the drying chamber 63 is set to run through the disinfection wheel 6 along the thickness direction of the disinfection wheel 6.

[0051] The steam supply is uninterrupted. When the steam inlet 11 is opposite to the connecting hole, some steam can enter the interior of the cavity 65. When the sterilization wheel 6 rotates, the steam will continue to enter the area between the two sterilization wheels 6. At this time, the steam in the area between the two sterilization wheels 6 will enter the drying chamber 63 inside the dispersion column 64.

[0052] When the nutrient soil is sterilized by contacting steam in the cavity 65, the moisture in the steam will have a certain impact on the nutrient soil, that is, it will stick together or adhere more easily to the inner wall of the cavity 65 or the dispersion column 64. Therefore, in this embodiment, a drying chamber 63 is formed inside the dispersion column 64. In addition to sterilizing the nutrient soil, the steam can also dry the nutrient soil participating in the sterilization process, so that the nutrient soil is kept as dry and dispersed as possible, thereby improving the sterilization effect.

[0053] In some further embodiments, there are multiple disinfection chambers 100, which are arranged vertically. The nutrient soil outlet 12 in the upper disinfection chamber 100 is connected to the nutrient soil inlet 10 in the lower disinfection chamber 100. The drive shafts corresponding to the disinfection wheels 6 in any two adjacent disinfection chambers 100 are meshed with each other by gears, and the connecting ports 60 correspond to each other during the meshing rotation.

[0054] In some further embodiments, the number of disinfection chambers 100 is two.

[0055] Based on the foregoing description of the structure and working principle of the disinfection chamber 100, in some other embodiments, the number of disinfection chambers 100 can be multiple, specifically two. The working principle and part of the structure when the number of disinfection chambers 100 is two are explained exemplarily.

[0056] Gears can be installed on the rotating shafts 62 corresponding to the two disinfection chambers 100 and mesh with each other. The reason for ensuring the synchronous operation of the two is to ensure that the connecting ports 60 on the disinfection wheels 6 in the two disinfection chambers 100 can be connected precisely when they stop, so that the nutrient soil after being disinfected in the upper disinfection chamber 100 can smoothly enter the lower disinfection chamber 100 for secondary disinfection, thereby improving the disinfection effect.

[0057] The outer walls of the upper disinfection wheel 6 and the lower disinfection wheel 6 are in contact with each other.

[0058] It can be concluded that the upper disinfection wheel 6 and the lower disinfection wheel 6 rotate in opposite directions due to the meshing of the rotating shaft 62. In other words, the nutrient soil is flipped in the upper disinfection wheel 6 in the opposite direction to the lower disinfection wheel 6, which further ensures the chaotic and dispersing effect of the nutrient soil and avoids accumulation, clumping or sticking.

[0059] In some further embodiments, a sliding block 2 is provided below the lowest disinfection chamber 100. The sliding block 2 is reciprocating and is provided with a V-shaped groove 20 that extends vertically through the sliding block 2.

[0060] The nutrient soil that comes out of the nutrient soil outlet 12 of the sterilization chamber 100 will enter the V-shaped groove 20. The V-shaped groove 20 is opened in the sliding block 2, and the sliding block 2 can reciprocate in a certain straight direction, specifically in a straight line direction perpendicular to the rotation axis 62 in the horizontal plane.

[0061] The nutrient soil that enters the V-shaped groove 20 will be continuously patted by the two side walls of the V-shaped groove 20 and move towards the bottom of the V-shaped groove 20. During the process, the nutrient soil is repeatedly broken up and will gradually form a straight line along the axis of rotation 62, that is, it will fall from the bottom of the V-shaped groove 20 as much as possible with a "planar" structure.

[0062] It should be noted that the nutrient soil falling in a "flat" structure may have a certain degree of curvature, but its thickness along the swing direction is relatively thin to ensure that the sprayed nutrient solution is fully mixed with the nutrient soil.

[0063] In some further embodiments, the sliding block 2 is provided with a sliding groove 23, and the outer side of the disinfection chamber 100 is provided with a sliding rail 21, which slides in conjunction with the sliding groove 23.

[0064] For example, the sliding block 2 is achieved through the sliding engagement of the sliding groove 23 and the sliding rail 21 located outside the disinfection chamber 100.

[0065] Please refer to Figure 11Furthermore, in some other embodiments, a sliding column 24 can be provided in the slide groove 23, and a wave-shaped slit 22 is provided through the slide rail 21 along the length of the sliding column 24. The sliding column 24 is slidably disposed in the wave-shaped slit 22. In order to accommodate the swaying redundancy of the sliding block 2 during the cooperation between the wave-shaped slit 22 and the sliding column 24, the dimension of the slide rail 21 in the height direction is made smaller than the dimension of the slide groove 23 in the height direction. At the same time, elastic elements are provided in the two gaps formed in the height direction between the slide rail 21 and the slide groove 23 to ensure the stability and recovery of the sliding block 2 during fluctuation. Specifically, the elastic element can be an elastic steel sheet 26 with an arc-shaped structure. Adaptively, limiting grooves 25 are provided on the side walls of the slide groove 23 and the side walls of the slide rail 21 to accommodate the elastic steel sheet 26 and limit the degree of compression or sliding of the elastic steel sheet 26.

[0066] The number of elastic steel sheets 26 and limiting grooves 25 can be set in multiples, such as three at intervals along the sliding direction of the sliding block 2, and all arranged on the upper and lower sides of the slide rail 21.

[0067] With the cooperation of the sliding column 24 and the wave slit 22, the sliding block 2 can slide along the slide rail 21 and also oscillate back and forth in the up and down direction, so that the inner wall of the V-shaped groove 20 can disperse the nutrient soil in multiple directions, thereby making the nutrient soil to be sprayed with nutrient solution more evenly dispersed, so as to ensure the spraying effect of nutrient solution.

[0068] In some further embodiments, a connecting handle 4 is hinged to the sliding block 2, a motor 5 is provided outside the disinfection chamber 100, a rotating disk 40 is provided at the transmission end of the motor 5, and the connecting handle 4 is hinged to the non-center part of the rotating disk 40.

[0069] For example, the reciprocating motion of slider 2 can be achieved using a crank-slider-like structure.

[0070] In some further embodiments, the disinfection chamber 100 is provided with two mounting brackets 3 at intervals on the outside. The two mounting brackets 3 are located on both sides of the swing direction of the sliding block 2, and nutrient solution spray pipes 30 are provided on the opposite side of the mounting brackets 3.

[0071] The V-shaped groove 20 is designed to tap the nutrient soil, further reducing compaction, adhesion, or sticking. It also allows the nutrient soil to fall in a "flat" or "water curtain" pattern, making it easier for the sprayed nutrient solution to fully integrate with the nutrient soil.

[0072] The number of nutrient solution spray pipes 30 can be set in the vertical direction, and the nutrient solution spray pipes 30 on the left and right mounting frames 3 can be staggered so that the nutrient soil is in a fluctuating state during the falling process, thereby increasing the degree of mixing.

[0073] In other embodiments, the nutrient solution spray pipes 30 located at the bottom of the two mounting brackets 3 can be arranged opposite each other to ensure that the final nutrient soil can fall smoothly into the conveying structure or a container.

[0074] Please refer to Figure 10 In some further embodiments, a limiting net 7 is provided at the bottom of the sliding block 2. There are two limiting nets 7, which are spaced apart on both sides of the bottom opening of the V-shaped groove 20 along the sliding direction of the sliding block 2. After setting the limiting nets 7, firstly, it can prevent the nutrient soil from being excessively deflected or scattered under the impact of the spraying of nutrient solution. Secondly, it can form a certain area between the two limiting nets 7, so that the sprayed nutrient solution is not only mixed with the nutrient soil in a certain area that intersects with the nutrient soil, but is continuously mixed in the space area formed between the two limiting nets 7. Compared with the former, after setting the limiting nets 7, the mixing of nutrient soil and nutrient solution will be more thorough. That is to say, under the combination of the falling motion of nutrient soil, the lateral shaking of nutrient soil, and the irregular movement of nutrient solution between the two limiting nets 7, nutrient solution and nutrient soil will be fully mixed.

[0075] In practice, the limiting net 7 can be made of soft net, and its edges can be set with a square frame, which is more common in existing technologies, for posture fixation, so as to form a plate-like structure.

[0076] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
