Detailed implementation manners

[0018] Now, the present application will be further described in detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, so they only show the components related to the present application.

[0019] As Figures 1-8 shown, a nutrient soil disinfection and sterilization device for soil treatment includes a disinfection and sterilization chamber 100 and a plurality of disinfection wheels 6 rotatably arranged in the disinfection and sterilization chamber 100. A cavity 65 is provided inside the disinfection wheel 6, and a number of dispersion columns 64 are provided in the cavity 65; a communication port 60 is provided on the peripheral wall of the cavity 65; a nutrient soil feed inlet 10 is provided at the top of the disinfection and sterilization chamber 100, a nutrient soil discharge outlet 12 is provided at the bottom, and steam inlets 11 are provided on the left and right sides.

[0020] The disinfection and sterilization chamber 100 can be the internal area of a certain housing structure, and an example can be a housing formed by enclosing a plate-like structure such as by welding.

[0021] The disinfection wheel 6 is preferably in a disc-shaped structure and can rotate in the cavity 65. In particular, the rotation of the disinfection wheel 6 can be achieved through the rotating shaft 62. For example, the rotating shaft 62 penetrates the disinfection chamber 100, and the disinfection wheel 6 is arranged on the rotating shaft 62. The realization of the rotating shaft 62 can be achieved through the servo motor 5 or a driving mechanism formed by the combination of the servo motor 5 and a speed reducer. For example, it can be achieved by setting a specific rotation program through the PLC controller.

[0022] A cavity 65 is provided inside the disinfection wheel 6. Preferably, the overall external contour of the disinfection wheel 6 is in a columnar structure, and the cavity 65 inside it is also in a columnar structure.

[0023] A plurality of dispersing columns 64 are distributed inside the disinfection wheel 6. The dispersing columns 64 are arranged at intervals from each other so that the nutrient soil can be fully dispersed when flowing inside the disinfection wheel 6, thereby ensuring sufficient mixing with the steam.

[0024] A plurality of disinfection wheels 6 are arranged axially at intervals on the rotating shaft 62, and the positions of the communication ports 60 on each disinfection wheel 6 are opposite to each other.

[0025] The nutrient soil inlet 10 provided at the top of the disinfection chamber 100 is used for feeding, the nutrient soil outlet 12 provided at the bottom is used for discharging, and the steam inlets 11 provided on the left and right sides are used to introduce high-temperature steam into the disinfection chamber 100.

[0026] Exemplarily, the internal contour of the disinfection chamber 100 fits well with the occupied volume of the plurality of disinfection wheels 6. Specifically, the disinfection chamber 100 is a cylindrical area, and the plurality of disinfection wheels 6 also form a cylindrical area, and the cylindrical area formed by the disinfection wheels 6 is as large as possible equal to the cylindrical area of the disinfection chamber 100 to increase the effective treatment area of the steam on the nutrient soil.

[0027] It should be noted that in some embodiments, when the number of disinfection wheels 6 is arranged in multiple along the axial direction of the rotating shaft 62, a baffle will be provided on the nutrient soil inlet 10 at the top of the disinfection chamber 100. The baffle is directly above the area between two disinfection wheels 6 to prevent the nutrient soil from entering the area outside the disinfection wheel 6.

[0028] The entry and exit of the nutrient soil and the entry of the high-temperature steam both enter through the communication port 60.

[0029] The nutrient soil is conveyed to the top of the disinfection chamber 100 through a conveying device, such as a conveyor belt. At this time, one of the communication holes in the disinfection wheel 6 corresponds to the nutrient soil feed port 10. The nutrient soil on the conveyor belt enters the inside of the disinfection wheel 6 through the nutrient soil feed port 10 and the communication 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 in 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 and there is no need to additionally set a dispersion mechanism with an energy-driven nature, thus reducing the energy consumption for treating the nutrient soil. In addition, the inside of the disinfection wheel 6 is a circular structure. When the steam enters the inside of the disinfection wheel 6, it can be dispersed in the cavity 65, and due to the action of the dispersion column 64, the steam can be further mixed evenly inside the cavity 65, so as to contact the nutrient soil more fully and achieve full sterilization.

[0030] In addition, in some other embodiments, the disinfection wheel 6 can rotate, and the conveyor belt for conveying the nutrient soil can also be set to move intermittently. Exemplarily, a movement form can be formed: when a certain communication port 60 in the disinfection wheel 6 is facing the nutrient soil feed port 10, the conveyor belt moves normally. At this time, the nutrient soil enters the inside of the disinfection wheel 6 through the nutrient soil feed port 10 and the corresponding communication hole. When the nutrient soil descends and disperses through the dispersion column 64, the conveyor belt can stop conveying, and at the same time, the disinfection wheel 6 can rotate. The introduction of steam always operates throughout the process. When the disinfection wheel 6 rotates, the nutrient soil entering the central part of the area formed by the multiple dispersion columns 64 will move from the central part to the edge part, so that the nutrient soil changes its original falling path, increasing its chaos and disorder, thereby further improving the mixing degree with the steam to ensure more complete disinfection. At the same time, intermittently rotating the disinfection wheel 6 can prevent the accumulation of nutrient soil on the dispersion column 64, and then avoid causing blockage in the area of the dispersion column 64.

[0031] In some further embodiments, the dispersion columns 64 are arranged vertically in rows and columns to form a square column group; the number of communication ports 60 is four, and the four communication ports 60 are circumferentially spaced. The four corner positions of the square column group are respectively arranged corresponding to the four communication ports 60.

[0032] Arranged vertically in rows and columns means that multiple dispersion columns 64 are arranged in multiple rows and columns, and the extending direction of each row is perpendicular to the extending direction of each column. Moreover, the number of dispersion columns 64 in each row is the same as the number of dispersion columns 64 in each column.

[0033] Since all the dispersion columns 64 form a square column group, the square column group forms four corner positions. One corresponding dispersion column 64 at each corner position exactly corresponds to one communication port 60. That is to say, when the nutrient soil enters the disinfection wheel 6 from the communication port 60, it will pass through the right triangle areas formed by multiple dispersion columns 64, and then pass through the right triangle areas formed by multiple inverted dispersion columns 64 on the other half, and thus be discharged from the nutrient soil discharge port 12 at the bottom; during the whole process, the area that the nutrient soil passes through is two right triangle areas formed by multiple dispersion columns 64, one upright and one inverted. It should be noted that the first upright right triangle area conforms to the structure of the Dalton plate, and the other inverted right triangle area also conforms to the structure of the Dalton plate. Therefore, when the nutrient soil enters the first upright right triangle area, the amount of nutrient soil falling in the central part will account for a relatively large proportion. And when it all enters the inverted right triangle area, the nutrient soil will finally concentrate and fall from the middle part at the bottom of the inverted triangle, that is, as directly as possible from the nutrient soil discharge port 12. One reason is that the nutrient soil falling from the first upright right triangle area conforms to the normal distribution, and when these nutrient soils enter the inverted right triangle area, they still enter in a state of presenting the normal distribution. Therefore, most of the finally falling nutrient soil still falls at the middle position below the inverted right triangle area, that is, at the nutrient soil discharge port 12. The second reason is that in the inverted right triangle area, the largest upright right triangle area that can be selected is the middlemost area. Therefore, assuming that there are countless upright right triangle areas in the inverted right triangle area, it must be the upright right triangle area in the middlemost area that has the largest area. Therefore, the nutrient soil falling in the normal distribution from the first upright right triangle area will still fall from the inverted right triangle area in a form similar to the normal distribution or concentrated in the middle, so as to fall as close as possible to the vicinity of the nutrient soil discharge port 12, thus ensuring the discharge efficiency.

[0034] In some further embodiments, the number of cavities 65 on the disinfection wheel 6 is two, and the two cavities 65 are respectively located on both sides of the disinfection wheel 6.

[0035] 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 that, on the one hand, it can provide installation positions for the dispersion columns 64 and the rotating shaft 62, and on the other hand, it can strengthen the structural strength of the whole disinfection wheel 6.

[0036] It should be thought that increasing the number of cavities 65 will also improve the processing efficiency of the nutrient soil.

[0037] In some further embodiments, adjacent disinfection wheels 6 are spaced apart; a drying cavity 63 is provided inside the dispersion column 64, and any drying cavity 63 communicates with partial areas of the disinfection chambers 100 on both sides of the disinfection wheel 6.

[0038] Please refer to Figure 9 , the dispersion column 64 is a hollow structure as a whole, that is, the internal drying cavity 63 is formed; the drying cavity 63 penetrates through the disinfection wheel 6 as a whole along the thickness direction of the disinfection wheel 6.

[0039] The introduction of steam is continuous. When the steam inlet 11 is opposite to the communication hole, part of the steam can enter the inside of the cavity 65, and when the disinfection wheel 6 rotates, the steam will continue to enter the area between the two disinfection wheels 6. At this time, the steam in the area between the two disinfection wheels 6 will enter the drying cavity 63 inside the dispersion column 64.

[0040] When the nutrient soil is disinfected by contacting with steam in the cavity 65, the moisture in the steam will have a certain impact on the nutrient soil, that is, it will stick to each other or more easily adhere to the inner wall of the cavity 65 or the dispersion column 64. Therefore, in this embodiment, a drying cavity 63 is formed inside the dispersion column 64. In addition to disinfecting the nutrient soil, the steam can also dry the nutrient soil participating in the disinfection process, so that the nutrient soil can be kept dry and dispersed as much as possible, thereby improving the disinfection effect.

[0041] In some further embodiments, the number of disinfection chambers 100 is multiple, and the multiple disinfection chambers 100 are arranged in the up-down direction. The nutrient soil discharge port 12 in the upper disinfection chamber 100 communicates with the nutrient soil feed port 10 in the lower disinfection chamber 100; the transmission shafts corresponding to the disinfection wheels 6 in any two adjacent disinfection chambers 100 are meshed with each other through gears, and the communication ports 60 correspond to each other during the meshing rotation.

[0042] In some further embodiments, the number of disinfection chambers 100 is two.

[0043] 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. Exemplarily, the working principle and some structures when the number of disinfection chambers 100 is two are described.

[0044] Gears can be provided on the rotating shafts 62 corresponding to the two disinfection chambers 100 and meshed with each other. The reason for ensuring their synchronous operation is to make the communication ports 60 on the disinfection wheels 6 in the two disinfection chambers 100 exactly dock when stopped, so that the nutrient soil disinfected in the upper disinfection chamber 100 can smoothly enter the lower disinfection chamber 100 for secondary disinfection, thereby improving the disinfection effect.

[0045] The outer peripheral walls of the upper disinfection wheel 6 and the lower disinfection wheel 6 are in contact with each other.

[0046] It can be concluded that due to the meshing of the rotating shafts 62, the rotation directions of the upper disinfection wheel 6 and the lower disinfection wheel 6 are exactly opposite. That is to say, the turning direction of the nutrient soil in the upper disinfection wheel 6 is exactly opposite to that in the lower disinfection wheel 6, further ensuring the chaotic dispersion effect of the nutrient soil and avoiding accumulation, caking or adhesion.

[0047] In some further embodiments, a sliding block 2 is provided below the lowermost disinfection chamber 100. The sliding block 2 is reciprocally movable. A V-shaped groove 20 is provided in the sliding block 2, and the V-shaped groove 20 penetrates the sliding block 2 vertically up and down.

[0048] The nutrient soil coming out of the nutrient soil discharge port 12 of the disinfection chamber 100 will enter the V-shaped groove 20. The V-shaped groove 20 is provided in the sliding block 2, and the sliding block 2 can reciprocate in a certain linear direction, specifically a linear direction perpendicular to the rotating shaft 62 in the horizontal plane.

[0049] The nutrient soil entering the V-shaped groove 20 will be continuously slapped by the two side walls of the V-shaped groove 20 and move towards the bottom of the V-shaped groove 20. During the whole process, the nutrient soil is repeatedly dispersed and will gradually form a straight line along the axial direction of the rotating shaft 62, that is, it will fall from the bottom of the V-shaped groove 20 in an "as flat as possible" structure.

[0050] It should be noted that the nutrient soil falling in an "as flat as possible" structure may have a certain curved state, but the thickness in the swinging direction is relatively thin to ensure that the sprayed nutrient solution is fully mixed with the nutrient soil.

[0051] In some further embodiments, a sliding groove 23 is provided in the sliding block 2, and a sliding rail 21 is provided outside the disinfection chamber 100. The sliding rail 21 is slidably engaged with the sliding groove 23.

[0052] Exemplarily, the sliding of the sliding block 2 is realized through the sliding cooperation of the sliding groove 23 and the sliding rail 21 provided outside the disinfection chamber 100.

[0053] Please refer to Figure 11, Further, in some other embodiments, a sliding column 24 may be provided in the sliding groove 23. Correspondingly, a wavy slot 22 is provided through the sliding rail 21 along the length direction of the sliding column 24. The sliding column 24 is slidably arranged in the wavy slot 22. And, in order to adapt to the sloshing redundancy of the sliding block 2 during the cooperation between the wavy slot 22 and the sliding column 24, the dimension of the sliding rail 21 in the height direction is particularly made smaller than the dimension of the sliding groove 23 in the height direction. At the same time, elastic members are provided in the two gaps formed in the height direction between the sliding rail 21 and the sliding groove 23 to ensure the stability and resilience of the sliding block 2 during fluctuations; specifically, the elastic member may be an elastic steel sheet 26, and the elastic steel sheet 26 has an arc-shaped structure. Adaptively, limiting grooves 25 are provided on the side walls of both the sliding groove 23 and the sliding rail 21 for arranging the elastic steel sheet 26 to limit the degree of compression or sliding of the elastic steel sheet 26.

[0054] The number of the elastic steel sheets 26 and the limiting grooves 25 may be set to be multiple, such as three are arranged at intervals along the sliding direction of the sliding block 2, and all are arranged on the upper and lower sides of the sliding rail 21.

[0055] Under the cooperation of the sliding column 24 and the wavy slot 22, the sliding block 2 can reciprocate in the up and down direction while sliding along the sliding rail 21, so that the inner wall of the V-shaped groove 20 disperses the nutrient soil in multiple directions, and then makes the nutrient soil to be sprayed with nutrient solution more dispersed and uniform, so as to ensure the spraying effect of the nutrient solution.

[0056] In some further embodiments, a connecting handle 4 is hingedly provided on the sliding block 2, a motor 5 is provided outside the disinfection chamber 100, and a rotating disc 40 is provided at the transmission end of the motor 5. The connecting handle 4 is hingedly connected to a non-central part of the rotating disc 40.

[0057] Exemplarily, the reciprocating motion of the sliding block 2 can be realized by a structure similar to a crank-slider.

[0058] In some further embodiments, two mounting brackets 3 are provided at intervals outside the disinfection chamber 100. The two mounting brackets 3 are respectively located on both sides of the swinging direction of the sliding block 2. Nutrient solution spraying pipes 30 are provided on the mutually facing sides of the mounting brackets 3.

[0059] The reason for setting the V-shaped groove 20 is that, on the one hand, it can beat the nutrient soil to further reduce hardening, adhesion or sticking, and on the other hand, it makes the nutrient soil present a "plane" or "water curtain" state during the falling process, so that the sprayed nutrient solution can be more easily and fully mixed with the nutrient soil when spraying the nutrient solution.

[0060] The number of the nutrient solution spraying pipes 30 can be set in the up and down direction, and the nutrient solution spraying pipes 30 on the left and right mounting brackets 3 can be arranged staggeredly, so that the nutrient soil during the falling process is in a fluctuating state to increase the mixing degree.

[0061] In other embodiments, the nutrient solution spraying pipes 30 at the bottom of the two mounting brackets 3 can be arranged oppositely to ensure that the final nutrient soil can smoothly fall onto the conveying structure or a certain container.

[0062] Please refer to Figure 10 , in some further embodiments, a limiting net 7 is provided at the bottom of the sliding block 2. The number of the limiting nets 7 is two. The two limiting nets 7 are arranged at intervals along the sliding direction of the sliding block 2 on both sides of the bottom opening of the V-shaped groove 20. After the limiting net 7 is provided, firstly, it can prevent the nutrient soil from excessively shifting or scattering under the spraying impact of the 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 intersecting with the nutrient soil, but is continuously mixed in the space area formed between the two limiting nets 7. Compared with the former, after the limiting net 7 is provided, the mixing of the nutrient soil and the nutrient solution will be more sufficient. That is to say, under the combination of the falling movement of the nutrient soil, the lateral vibration of the nutrient soil, and the random movement of the nutrient solution between the two limiting nets 7, the nutrient solution and the nutrient soil will be fully mixed.

[0063] In actual situations, the limiting net 7 can be made of a soft net, and its edge can be provided with a square frame relatively common in the prior art for attitude fixation to form a plate-like structure.

[0064] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
