Description

Technical Field

[0001] The invention relates to the technical field of fertilizer preparation, in particular to a method for preparing organic fertilizer from residues left after dead pets are incinerated. Background Art

[0002] As people's emotional dependence on pets increases, the number of pets increases year by year, and with it comes the issue of harmless disposal of pets after death. At present, one of the more common disposal methods is to achieve harmless disposal through high-temperature incineration. The residues after incineration mainly include slag and fly ash, among which slag can be converted into organic fertilizer or other resource products through certain processing, which not only solves the problem of waste disposal, but also realizes the recycling of resources.

[0003] In the process of converting the incinerated residue into organic fertilizer, mixing is a crucial step. Existing mixing equipment has shortcomings in handling this type of special raw materials. Since the physical properties of the residue after the incineration of dead pets are different from those of traditional organic fertilizer raw materials, traditional mixing equipment often cannot achieve the ideal mixing effect, resulting in low mixing efficiency;

[0004] In addition, due to the large differences in density between the raw materials and the fact that some of the raw materials may contain harder substances (such as bone ashes), agglomeration is likely to occur during the mixing process, which in turn affects the quality of the final product. At the same time, in order to achieve a better mixing effect, existing mixing equipment often needs to operate for a long time, which not only increases energy consumption but also reduces production efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide a method for preparing organic fertilizer from the residue after burning dead pets, which has the advantages of improving the quality of organic fertilizer products, reducing energy consumption, and improving production efficiency, and solves the problems of low mixing efficiency, uneven mixing, high energy consumption, and difficulty in adapting to different raw material ratios when processing the residue after burning dead pets and other organic fertilizer raw materials.

The transmission shaft sleeve 560 can rotate with the transmission shaft 550, and when the transmission shaft sleeve 560 is pulled up and down by the guide seat 542, it can drive the transmission shaft sleeve 560 to rotate on the transmission shaft 550 and move back and forth up and down.

[0087] The end of the driving shaft 500 is sleeved with a connecting seat 520, and the connecting seats 520 are used in combination, and the tail ends of the two connecting seats 520 on the opposite side are movably installed with a gear member 521 through a bearing, wherein the gear member 521 and the ring gear member 410 are meshed with each other, and the other end of the connecting seat 520 is connected to a scraper plate 530, wherein the surface of the scraper plate 530 passes through the guide groove hole 421 and extends to the inner cavity of the mounting platform 400, so that when the scraper plate 530 rotates, it can scrape different raw materials in its inner cavity and disperse them into the proportioning tank 100, and when the scraper plate 530 rotates, it can move the sealing slip ring 420 in the mounting slide groove 401, so that it does not hinder the movement of the scraper plate 530 and can seal the mounting platform 400;

[0088] In order to adjust the position of the transmission sleeve 560 so that it can move up and down reciprocatingly when rotating, a transmission sleeve 540 is sleeved on the end of the surface of the driving shaft 500, and a reciprocating screw 541 is inlaid on the surface of the driving shaft 500. The transmission sleeve 540 and the reciprocating screw 541 are existing mechanical design standard parts structures. This solution does not elaborate on the connection method between the two. The reciprocating screw 541 is used in conjunction with the transmission sleeve 540 and can be forced to reciprocate up and down in a straight line. Therefore, the transmission sleeve 560 is pulled to move. The outer surface of the transmission sleeve 540 is sleeved with a guide seat 542, wherein the transmission sleeve 560 is movably sleeved on the inner surface of the guide seat 542 through a bearing, and the outer surface of the transmission shaft 550 is integrally formed with a limit strip 551, and the transmission sleeve 560 The inner surface is provided with a limiting groove cavity 561 used in conjunction with the limiting strip 551, wherein the connection between the two is lubricated. Therefore, when the transmission shaft 550 rotates, the transmission sleeve 560 can be driven to rotate under the action of the limiting strip 551 and the limiting groove cavity 561, and when the guide seat 542 moves up and down, the transmission sleeve 560 can be pulled to rotate and move up and down, thereby driving the stirring blade 570 to be pulled, and the raw materials in the proportioning tank body 100 are effectively stirred. The tail end of the transmission sleeve 560 is connected to a wall scraper body 580, and the wall scraper body 580 is made of a flexible material and has a certain curvature, wherein the wall scraper body 580 is in sliding contact with the inner wall of the proportioning tank body 100, thereby under the action of the wall scraper body 580, the inner wall of the proportioning tank body 100 is effectively cleaned.

[0089] During the operation of the proportioning and mixing equipment, various fertilizer raw materials are respectively fed into the corresponding storage tanks 200, and then fed into the mounting table 400 after proportioning and adjustment. When the driving part 300 is working, the driving shaft 500 can be forced to rotate, and then drive the transmission shaft 550 and the connecting seat 520 to move respectively. The connecting seat 520 moves to drive the scraping plate 530 to rotate. The scraping plate 530 rotates to move the raw materials entering the mounting table 400, so that they are dispersed and fall into the proportioning tank 100, and the fertilizer raw materials are fed at multiple points to avoid the problem of uneven mixing caused by traditional feeding in one direction, which increases the dispersion and stirring efficiency.

[0090] After the raw materials fall into the proportioning tank 100, the transmission shaft 550 can rotate under the cooperation of the gear member 521 and the ring gear member 410, and under the action of the driving shaft 500, it can rotate around the driving shaft 500 while rotating on its own, so that the stirring blade 570 can effectively and fully stir and disperse the various fertilizer raw materials in the proportioning tank 100;

[0091] Furthermore, when the driving shaft 500 rotates, the transmission sleeve 540 and the reciprocating screw 541 cooperate to drive the guide seat 542 to move up and down, and finally pull the transmission sleeve 560 to move up and down, so that the stirring blade 570 can not only rotate on its own and move in a circle around the driving shaft 500, but also be pulled up and down, thereby increasing the mixing efficiency of the powder in the proportioning tank 100.

[0092] At the same time, when the driving shaft 500 rotates, the spiral blade 510 can be driven to rotate, so that the material flowing into the guide tube 140 from the bottom of the proportioning tank 100 can be transported upward, avoiding the material at the bottom of the proportioning tank 100 from being deposited all the time, solving the problem of uneven deposit and mixing at the bottom, so as to evenly mix the residue after incineration with other fertilizer raw materials;

[0093] When using the residues after burning dead pets to prepare organic fertilizer, according to the production requirements of NY525, the crushed and sieved residues after burning, organic matter (≥45%; 60 mesh, 246μm), urea, diammonium phosphate, potassium sulfate, potassium chloride and other macroelements (N+P203+K20≥5%; 60 mesh, 246μn), attapulgite, bentonite, white clay, kaolin and the like (120 mesh, particle size 120μm), etc., are weighed in proportion, the water content is controlled to 25-35%, and the mixture is evenly mixed to prepare the fertilizer;

[0094] When using the residues after the incineration of dead pets to prepare organic-inorganic compound fertilizers, according to the production requirements of GB18877, the crushed and sieved residues after incineration, organic matter (≥20% or ≥15%; 60 days, 246μm), urea, diammonium phosphate, potassium sulfate, potassium chloride and other macroelements (N+P203+K20≥15% or ≥25%; 60 mesh, 246μm), attapulgite, bentonite, white clay, kaolin and the like (120 days, particle size 120μm), etc., are weighed in proportion, the water content is controlled to be 12%-15%, and the mixture is evenly mixed to prepare the fertilizer;
