It is further understood that the embodiments described herein are not mutually exclusive of one another but can be combined under certain circumstances.

[0043] A raw material receiving and conditioning device for organic fertilizer is described in detail below with reference to the accompanying drawings.

[0044] As Figure 1As shown, an organic fertilizer raw material receiving and conditioning device includes a top-closed pre-settling tank 21 and a second soaking tank 22; the bottoms of the pre-settling tank 21 and the second soaking tank 22 are connected, and the material in the pre-settling tank 21 is conveyed to the second soaking tank 22 by a first conveying device 23; the pre-settling tank 21 is provided with a feed inlet, specifically, the feed inlet of the pre-settling tank 21 is provided with a cover plate that can be rotated and opened; the pre-settling tank 21 is provided with a first agitator 24 to agitate the material in the tank; the second soaking tank 22 is provided with a second agitator 25 to agitate the material in the tank; the liquid in the upper part of the second soaking tank 22 is conveyed to the pre-settling tank 21 by a circulating pump 26, and the material at the bottom is discharged.

[0045] Preferably, the bottom outlet of the second soaking tank 22 is located on the side away from the pre-sedimentation tank 21, and the second soaking tank 22 is inclined toward the bottom outlet with an inclination angle of K (angle with the horizontal direction), 15°≤K≤30°, so as to facilitate discharge.

[0046] The organic fertilizer raw material receiving and conditioning equipment of the present invention, based on the setting of a pre-sedimentation tank and a second soaking tank, removes impurities such as mud and stones from manure and / or straw raw materials. The first agitator and the first conveying device work together to improve the impurity removal rate. With the addition of the second agitator, the impurity removal rate can reach more than 95% (based on a sand and gravel content of 2-5% in the feed). This avoids equipment wear caused by subsequent processing such as dehydration. Furthermore, when the organic fertilizer raw material receiving and conditioning equipment of the present invention is used for straw soaking treatment, it can effectively shorten the straw soaking time, requiring only 3-4 hours to achieve saturated moisture content in dry straw (conventional processes require 6-12 hours).

[0047] In some embodiments, such as Figure 1 As shown, the included angle between the blade 2411 of the stirring paddle 241 of the first stirrer 24 and the rotating shaft 2412 is A, 30°≤A≤90°; if the angle is too small, the stirring effect will be poor; the first motor 242 of the first stirrer 24 is selected as a variable speed motor.

[0048] In some embodiments, such as Figure 2As shown, the first paddle 2411 of the first stirring blade 241 of the first stirrer 24 is hinged to the first rotating shaft 2412 (such as through a hinge), and the included angle between the two is continuously adjusted through the adjusting device 2413 (specifically, the angle is adjusted according to the viscosity of the material, and the higher the viscosity, the smaller the angle); the adjusting device 2413 includes a flexible rope 24131; one end of the flexible rope 24131 is connected to the first paddle 2411, and the other end extends out of the pre-sedimentation tank 21 through the inside of the first rotating shaft 2412 (a steel pipe can be selected as the first rotating shaft or the first rotating shaft 2412 has a passage for the flexible rope 24131 to pass through); the flexible rope 24131 is pulled to change the angle of the first paddle 2411; specifically, after adjusting the angle, the end of the flexible rope is fixed, such as being fixed on the first rotating shaft or other fixing methods.

[0049] In some embodiments, as shown in Figure 2 As shown, the adjusting device 2413 further includes a limiting piece 24132 (such as a limiting rod structure); the limiting piece 24132 is fixedly arranged on the flexible rope 24131; the first rotating shaft 2412 is provided with a limiting groove 24121 for accommodating the limiting piece 24132; the limiting groove 24121 extends axially along the first rotating shaft 2412, and the limiting angle of the first paddle 2411 is limited based on the cooperation between the limiting groove 24121 and the limiting piece 24132.

[0050] Specifically, the number of limiting grooves 24121 is 2, and the limiting grooves 24121 are oppositely arranged on the side walls of the first rotating shaft 2412, and the two ends of the limiting piece 24132 are located in the limiting grooves 24121.

[0051] In some embodiments, as shown in Figure 1 and 3 As shown, the first paddle 2411 is provided in two pairs, and the two pairs are arranged at an included angle of 90°. The pairs of first paddles 2411 are oppositely arranged on the two sides of the first rotating shaft 2412, and the pairs of first paddles 2411 are arranged at the same height or staggered at different heights, preferably at the same height, so that more uniform stirring effect can be obtained to facilitate the removal of impurities.

[0052] In some embodiments, as shown in Figure 2 As shown, the paddle 2411 is a flat spiral type (that is, a long strip plate is twisted to form, and the paddle with this structure has moderate resistance and better stirring effect).

[0053] In some embodiments, as shown in Figure 1 As shown, the number of second stirrers 25 is 2, and the two second stirrers 25 are used to stir the material in the second soaking tank 22, thereby improving the separation effect of impurities in the material, and when used for processing straw material, the efficiency of straw soaking is improved.

[0054] In some embodiments, as shown in Figure 1As shown, the angle between the second paddle 2511 of the second stirring paddle 251 of the second stirrer 25 and the second rotating shaft 2512 is B, B is 65°, preferably, the second paddle 2511 is a flat spiral type; the second stirring paddle 251 is driven to rotate by the second motor 252, and the structure of the second stirring paddle 251 is the same as that of the first stirring paddle except that the fixed angle of the second paddle 2511 is different.

[0055] In some embodiments, as shown in Figure 3 As shown, the second paddle 2511 is provided with two pairs, and the two pairs are at an angle of 90°. Specifically, the second paddle 2511 arranged in pairs is arranged on both sides of the second rotating shaft 2512, and the second paddle 2511 arranged in pairs has the same height or is staggered in height, preferably the same height, so that more uniform stirring effect can be obtained to facilitate the discharge of impurities and achieve more sufficient soaking process.

[0056] In some embodiments, as shown in Figure 1 As shown, the pre-sedimentation tank 21 is provided with a scraper device 29 at the bottom; the scraper device 29 is used to transport the sediment deposited in the pre-sedimentation tank 21 out of the pre-sedimentation tank 21; the lower part of the pre-sedimentation tank 21 is a funnel structure.

[0057] Preferably, the scraper device 29 is multiple in number, and the multiple scraper devices 29 are arranged side by side on the bottom surface of the pre-sedimentation tank 21. By arranging multiple scraper devices, the width of a single scraper device is reduced, thereby avoiding damage to the scraper device due to excessive width. Specifically, the scraper device 29 is two in number; the width of the bottom surface of the pre-sedimentation tank 21 is 0.8-1.2 m.

[0058] Further preferably, in order to facilitate the discharge of materials in the pre-sedimentation tank, the lower part of the pre-sedimentation tank 21 is a funnel structure with an inclination angle C, 45°≤C≤60°; too small an angle will cause material accumulation, and too large an angle will reduce the volume of the tank.

[0059] The lower part of the pre-sedimentation tank 21 is a funnel structure including a funnel part and a straight section part below the funnel part, and the height of the straight section part is 0.4-0.6 m.

[0060] In some embodiments, as shown in Figure 1 As shown, the first conveying device 23 is arranged in the pre-sedimentation tank 21 and is a shaftless stirring cage conveyor. The shaftless stirring cage is used to convey the materials in the pre-sedimentation tank, which can promote the separation of impurities in the materials and drop to the bottom of the tank on the one hand, and can ensure the conveying effect with low disturbance to the tank on the other hand. In combination with the first stirrer, the effect of impurity removal (sedimentation) can be effectively improved, and the conveying effect can be ensured.

[0061] Preferably, the first conveying device 23 is multiple in number, and the multiple first conveying devices 23 are arranged in parallel along the horizontal direction.

[0062] In some embodiments, as shown in Figure 4 The pitch between the blades of the shaftless stirring cage 231 of the first conveying device 23 is L, L is 200-300 mm; the pitch is too small to be not conducive to material conveying, and is too large to reduce the sand sinking effect; the shaftless stirring cage 231 is driven to rotate by the third motor 232.

[0063] In some embodiments, as shown in Figure 1 The first conveying device 23 and the first stirrer 24 are arranged in a vertical direction, and the first stirrer 24 is above, and specifically, the shaft line of the shaftless stirring cage 231 is horizontally arranged, such as parallel to the bottom surface of the pre-sedimentation tank 21; in this scheme, the first rotating shaft 2412 of the first stirrer is perpendicular to the shaft line of the shaftless stirring cage 231, so that the material stirred by the first stirrer moves downward and then changes the moving direction to move in a horizontal direction after passing through the shaftless stirring cage 231; based on this, the material is effectively dispersed to effectively remove impurities in the material. Preferably, the spacing between the first conveying device 23 and the first stirrer 24 is M, the height of the blade of the shaftless stirring cage 231 of the first conveying device 23 is N, and M≥1.5N; under this spacing condition, the first conveying device 23 and the first stirrer 24 can be ensured not to affect each other, and the sand sinking effect is ensured. Specifically, the height N of the blade of the shaftless stirring cage 231 is 300 mm.

[0064] In some embodiments, as shown in Figure 1 The material receiving and conditioning equipment of the organic fertilizer raw material further comprises a purification device 27; the inlet of the purification device 27 is communicated with the pre-sedimentation tank 21 and the second soaking tank 22, and the outlet is communicated with the outside.

[0065] In some embodiments, the purification device 27 comprises an air drafter 271 and a deodorization device 272 (such as an activated carbon adsorption device); the inlet of the air drafter 271 is communicated with the pre-sedimentation tank 21 and the second soaking tank 22, and the outlet is communicated with the inlet of the deodorization device 272; the outlet of the deodorization device 272 is communicated with the outside.

[0066] In some embodiments, the material receiving and conditioning equipment of the organic fertilizer raw material further comprises a first buffer tank 28; the first buffer tank 28 is used for supplying water to the pre-sedimentation tank 21.

[0067] The working steps of the material receiving and conditioning equipment of the organic fertilizer raw material of the present application are as follows:
