Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of organic fertilizer production, in particular, relates to a drying treatment equipment for producing organic fertilizer. BACKGROUND

[0002] Bio-organic fertilizer is an agricultural product combining the advantages of microbial fertilizer and traditional organic fertilizer, which is usually made of specific functional microorganisms and animal and plant residues (such as livestock and poultry manure, crop straw, etc.) through harmless treatment and composting. There are various types, including manure, compost, green manure, cake fertilizer, biogas fertilizer, etc. These fertilizers are rich in organic matter, providing various inorganic and organic nutrients for crops, and have the advantages of improving soil, fertilizing soil, improving soil nutrient activity, and purifying soil ecological environment. The main characteristics of organic fertilizer are that the nutrient elements are comprehensive: the nutrient elements contained in organic fertilizer are in organic state, which is difficult for crops to directly utilize. However, through the action of microorganisms, various nutrient elements can be slowly released to continuously supply nutrients to crops. In the production of organic fertilizer, drying is an important link, mainly used to remove water from organic materials for subsequent granulation and molding. Different raw materials and production processes have different requirements for drying. In traditional organic fertilizer production, the method of natural airing is used, that is, the materials are piled on the empty land and aired by natural wind. This method has low cost, but the airing time is long and is greatly affected by weather, which easily causes unstable quality of organic fertilizer.

[0003] The drying device for processing organic fertilizer disclosed in the patent with the patent number CN118705855A can effectively screen out caked fertilizer, and then fully break up the caked fertilizer, so that the subsequent fertilizer can be effectively dried, avoiding the problem of incomplete drying of the fertilizer and eliminating the influence of normal processing of the subsequent fertilizer and the quality of the processed fertilizer.

[0004] The existing organic fertilizer drying device has uneven distribution of fertilizer in the drying cavity, which affects the uniform transmission of heat, so that part of the fertilizer may not receive enough heat, resulting in uneven drying, incomplete drying of part of the blocky material, and difficulty in further improving the overall drying efficiency.

[0030] The first air inlet 7 and the second air inlet 8 are arranged on the opposite side walls of the drying box 1 respectively, and are connected with the hot air machine through the air supply pipe. The first air inlet 7 is used for guiding the hot air to one side of the bottom of the first screening component 9 to screen the first screening component 9. The second air inlet 8 is used for guiding the hot air to one side of the bottom of the second screening component 15.

[0031] The inner wall of the drying box 1 and the bottom of the top cover 2 of the drying box 1 are provided with heat insulation pads. The drying box 1 can be placed on the ground through the support 6, so as to place the material container under the discharge port 4.

[0032] In some embodiments, the first screening component 9 and the second screening component 15 can be connected with the side wall of the drying box 1 through springs, so as to improve the swing amplitude of the first screening component 9 and the second screening component 15 through the springs.

[0033] The first screening component 9 and the second screening component 15 are both arc-shaped plate structures. The first screening component 9 is driven to swing through the first rotating shaft 11. The first air inlet 7 blows hot air to the bottom of one side of the first screening component 9, so as to drive the first screening component 9 to swing through the air force, to shake and swing the material on the first screening component 9. In the process of swinging, the material is continuously screened and falls to the second screening component 15 below. The second screening component 15 is also driven to swing by the hot air blown by the second air inlet 8, so as to realize multiple screening of the material and ensure the complete drying effect of the material.

[0034] Preferably, please refer to Figure 3 and 4 As shown in the drawings, the first screening component 9 is provided with a plurality of first screen holes 19 in the form of strips. A plurality of first protrusions 20 are arranged on the inner concave surface of the first screening component 9. The plurality of first protrusions 20 are arranged perpendicularly to each of the first screen holes 19 and separate each of the first screen holes 19. The second screening component 15 is provided with a plurality of second screen holes 21 in the form of strips.

The plurality of second protrusions 22 are arranged perpendicularly to each of the second screen holes 21 and separate each of the second screen holes 21.

[0035] It can be understood that the first sieve member 9 and the second sieve member 15 are respectively provided with a strip-shaped first sieve hole 19 and a strip-shaped second sieve hole 21, which can realize the material falling into the first sieve member 9 and the second sieve member 15 by gravity, and the material is discharged through the first sieve hole 19 and the second sieve hole 21 respectively. A plurality of first convex strips 20 are arranged vertically with each strip-shaped first sieve hole 19 and separate each first sieve hole 19, and a plurality of second convex strips 22 are arranged vertically with each strip-shaped second sieve hole 21 and separate each second sieve hole 21, which is beneficial to disperse the material more finely, and cooperates with the swinging action of the first sieve member 9 and the second sieve member 15, realizes more frequent collision and vibration of the material, so that the material is more finely screened, and is more beneficial to improve the drying effect.

[0036] Preferably, the first convex strip 20 and the second convex strip 22 are both tapered structures at the top.

[0037] It can be understood that the first convex strip 20 and the second convex strip 22 are both tapered structures at the top, that is, through the pointed structure, the material falling and touching the first convex strip 20 and the second convex strip 22 can be more easily dispersed.

[0038] Preferably, please refer to Figure 2 It is shown that the first sieve member 9 is provided with a first side plate 10 on both sides in the width direction, and the second sieve member 15 is provided with a second side plate 16 on both sides in the width direction.

[0039] It can be understood that the first side plate 10 on both sides can block the material on the first sieve member 9 to prevent the material from easily overflowing and falling from both sides. Similarly, the second side plate 16 on both sides can also play a role in blocking the material, ensuring that the material can be dispersed sufficiently in the process of swinging, vibration and impact, and ensuring complete drying.

[0040] Preferably, please refer to Figure 2 and 3 It is shown that the length of the second sieve member 15 along the vertical projection of the drying box 1 is longer than the length of the first sieve member 9.

[0041] It can be understood that the projection length of the second sieve member 15 is longer than the first sieve member 9, that is, the area of the second sieve member 15 is larger than the area of the first sieve member 9, which can make the second sieve member 15 smoothly receive the material falling from the first sieve member 9.

[0042] Optionally, please refer to Figure 3 It is shown that the second sieve member 15 is provided with a material blocking part 23 on both sides in the length direction, and the material blocking part 23 is a solid plate structure.

[0043] It can be understood that, since the projection length of the second screening member 15 is longer than the length of the first screening member 9, in order to ensure that the material screened by the first screening member 9 can smoothly roll into the second screening member 15, the material falling into the material blocking part 23 can slide into the second screening member 15 by arranging the material blocking part 23 in a solid plate structure on both sides of the second screening member 15, thereby increasing the vibration times of the material and ensuring that the material is scattered before falling.

[0044] It should be noted that the width of the second screen hole 21 of the second screening member 15 is smaller than the width of the first screen hole 19 of the first screening member 9, so that the material is gradually screened.

[0045] Optionally, please refer to Figure 1 and 2 and 3, the drying treatment equipment for producing organic fertilizer further comprises a baffle 13, a second rotating shaft 14 and a connecting rope 12, the baffle 13 is arranged between the first screening member 9 and the second screening member 15, the bottom of the baffle 13 is connected with the second rotating shaft 14, both ends of the second rotating shaft 14 are rotatably connected with the side wall of the drying box 1, and both ends of the baffle 13 in the length direction are connected with both ends of the first screening member 9 through the connecting rope 12. Specifically, a plurality of through holes are arranged on the baffle 13.

[0046] In the optional embodiment, the length of the baffle 13 in the vertical projection of the drying box 1 is less than the length of the second screening member 15.

[0047] It can be understood that, by arranging the baffle 13 with arrayed through holes between the first screening member 9 and the second screening member 15, the material can be further scattered, and the baffle 13 is connected with the first screening member 9 through the connecting rope 12 and can swing together with the first screening member 9, so that the material can be inclined to fall from the baffle 13 to the second screening member 15, realizing multiple screening of the material, effectively ensuring that the material is completely dried, and ensuring the drying effect.
