Description

Technical Field

[0001] The present invention relates to a new material production technology, and in particular to a method and equipment for producing a new material with multiple-form particles. Background Art

[0002] At present, my country is in the stage of accelerated development of industrialization and urbanization. In urban construction or industrial development, a large amount of construction waste or industrial tailings and tailings are often generated. These construction waste or industrial tailings and tailings often contain many useful components, such as metallic iron, calcium oxide, magnesium oxide, manganese oxide and other substances. In the past, they were often not taken seriously and caused waste of resources. At present, the main processing processes for recyclable materials such as construction waste, industrial tailings or tailings in China are: hot pouring method, drum method, granulation wheel method, hot stuffy method. It is found in the implementation that when these recyclable materials are in a molten state, high-pressure air is used as a medium. The liquid recyclable materials are broken by shearing and other actions under the strong impact and cooling effect of the high-pressure airflow, and heat is exchanged with the high-pressure gas at the same time. These recyclable materials are broken under the combined action of the impact force of the high-pressure airflow, the condensation force of the air and the thermal expansion force of the recyclable materials to form spherical fine particles. The product obtained by this method has a smaller particle size and a narrower particle size distribution range. The slag condensation speed is the fastest, the free calcium oxide digestion is also the most thorough, and the crystal phases are evenly distributed.

[0003] The product particles produced using these recyclable materials can be used as projectiles in shot blasting machines, but the particles obtained by the prior art are mostly spherical. The effect of spherical projectiles in shot blasting machines is often not as good as that of irregularly shaped projectiles of various forms. Therefore, sometimes when the shot blasting machine is used, some irregularly shaped stones are mixed into the product particles to improve the performance of the shot blasting machine. However, the hardness of the stones is often not as high as that of the particles. After a period of use, they are often crushed into powder and cannot be used anymore. At this time, a new batch of projectiles needs to be replaced. At this time, the undamaged particles are often discarded together, resulting in a waste of recyclable material resources such as recyclable tailings, tailings and construction waste. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a method and equipment for producing a new multi-morphological particle material.

[0005] To achieve the above object, the present invention adopts the following technical solution: a method for producing a new multi-morphological particle material, comprising the following steps:

[0006] S1: Preparation of polymorphic aggregate: crush the raw material with a crusher, sieve and sort the crushed aggregate to obtain granular aggregate, wash the granular aggregate with water and then dry it to obtain dried granular aggregate; remove impurities such as mud, dust and other impurities on the surface of the raw material to ensure the cleanliness of the polymorphic aggregate, and ensure the uniformity of the aggregate particles by sieving.

[0007] S2: Surface treatment of polymorphic aggregate: The surface of the dried polymorphic aggregate is treated to make the outer surface of the polymorphic aggregate rough, thereby increasing the roughness of the surface of the polymorphic aggregate; increasing the adhesion of the aggregate surface to facilitate the subsequent liquid recyclable material to adhere to the surface of the polymorphic aggregate.

[0008] S3: Preheating of polymorphic aggregate: preheat the dried granular aggregate obtained in S1 at 550℃-700℃ for 45min-65min to obtain preheated granular aggregate; preheat the aggregate first to prevent the aggregate from suddenly entering the high-temperature liquid recyclable material. The sudden exposure to heat will cause the aggregate to break, making it impossible to ensure the uniformity of the finished product particle size. At the same time, it will also affect the firmness of the produced product and make the finished product easy to break.

[0009] S4: Preparation of mixed liquid of recyclable materials and aggregates: transfer the recyclable materials to the slag tank, maintain the temperature of the recyclable materials at 1300℃-1450℃, add thermosetting adhesive to the slag tank, stir well, add the granular aggregate preheated in S2 to the slag tank, and continue to stir to disperse the aggregate into the liquid recyclable materials; after adding the thermosetting adhesive to the recyclable materials, stir well to make the liquid recyclable materials have a certain viscosity, add the aggregates and stir well to disperse the aggregates into the solution. The viscous liquid recyclable materials will more easily adhere to the outer surface of the aggregates.

[0010] S5: Granulation of mixed liquid: Pour the mixed liquid of recyclable materials and aggregates obtained in S3 into the chute of the granulation equipment, enter the granulation equipment through the chute, and blow extremely cold gas into the granulation equipment to promote the granulation of the mixed liquid to form multi-morphological particles; at this time, the multi-morphological particles include irregular aggregate particles wrapped with recyclable materials on the outside and spherical particles.

[0011] S6: Polymorphic particle sorting: The polymorphic particles obtained in S4 are sorted to separate the polymorphic particles; spherical and non-spherical polymorphic particles are separated.

[0012] Preferably, S3 is a step-by-step heating method for preheating the polymorphic aggregate. S3: The specific operation steps for preheating the polymorphic aggregate are: (1) first preheating the surface-treated polymorphic aggregate in S2 at a temperature of 550-580°C for 20-25 minutes; (2) raising the preheating temperature to 600-625°C and preheating the polymorphic aggregate at this temperature for 10-15 minutes; (3) continuing to raise the preheating temperature to 650-680°C and preheating the polymorphic aggregate at this temperature for 5-10 minutes; (4) raising the preheating temperature to 690-700°C and preheating the polymorphic aggregate for 10-15 minutes. Using a step-by-step heating method to preheat the polymorphic aggregate prevents the aggregate from being directly preheated at a high temperature during preheating, which will cause thermal expansion during the heating process, and cracks will be generated during the thermal expansion process, thereby affecting the strength of the recyclable material wrapping.

[0013] Preferably, S5: during the granulation process of the mixed liquid, a stirring device is provided in the chute to continuously stir the liquid recyclable material in the chute, so that the mixed liquid is mixed evenly in the chute, and the polymorphic aggregate is prevented from sinking to the bottom, and the particles are prevented from sticking together and blocking the chute.

[0014] Preferably, in S5, the high-pressure gas nozzle of the granulation equipment is located below the chute mouth, the high-pressure gas nozzle is arranged obliquely upward, and the high-pressure extremely cold gas is ejected obliquely upward from the bottom of the chute mouth. The uniformity of the bonding of the recyclable material on the surface of the granular aggregate is increased, and the surface oxidation time is increased to increase the stability.

[0015] Preferably, the raw material in S1 is ore or tailings. Ores such as siderite or chalcopyrite with a higher specific gravity than recyclable materials can be selected as raw materials. When the mixed liquid enters the chute, the multi-morphological aggregate generally sinks gradually below. The high-pressure gas blows obliquely upward, which can make the multi-morphological aggregate rotate and roll obliquely upward, and the surface of the multi-morphological aggregate fully contacts the recyclable material, so that the surface of the multi-morphological aggregate is convenient for the recyclable material to be wrapped on the surface of the multi-morphological aggregate.

[0016] Preferably, the sieve used for screening in S1 is 4 mesh, 7 mesh, 15 mesh, 20 mesh or 30 mesh.

[0017] Preferably, 90-100 parts of liquid recyclable material, 1-1.5 parts of thermosetting adhesive, and 120-150 parts of preheated aggregate need to be added to the slag pot in S3.

[0018] Preferably, S6: sorting of polymorphic particles: the polymorphic particles are dropped into the middle of an inclined conveyor belt, and collecting buckets are provided at both ends of the conveyor belt to separate spherical particles and non-spherical polymorphic particles.

[0019] Preferably, the conveyor belt has an inclination angle of 15-30 degrees. When the granulated particles fall onto the inclined conveyor belt, the spherical particles will roll downward and fall into the collection bucket from one side, while the non-spherical particles cannot roll on the conveyor belt, so they will move to the other side driven by the conveyor belt and finally fall into the collection bucket from the other side of the conveyor belt.

[0020] Preferably, the aggregate in S1 is sieved and sorted, first filtered through a 4-mesh sieve, and then the aggregate outside the sieve is filtered through a 7-mesh sieve, and the aggregate in the 7-mesh sieve is taken for use, ensuring that the particle size of the aggregate is 3mm-5mm.

[0021] Compared with the prior art, the present invention has the following beneficial effects: (1) The process of the present invention can prepare irregularly shaped polymorphic particles with recyclable materials wrapped on the outside. When the polymorphic particles are put into a shot blasting machine and used as projectiles, the performance of the shot blasting machine can be improved. Moreover, the hardness of the outside of the polymorphic particles is the same as that of the granulated particles, which prolongs the service life of the polymorphic particles, fully utilizes them, and reduces resource waste. At the same time, it also has a sorting device that can sort spherical and non-spherical polymorphic particles, which is convenient for selecting particles of different shapes for use according to needs, or when mixed, it can control the mixing ratio of mixed spherical and irregular polymorphic particles. (2) During the process, the surface of the dried polymorphic aggregate is treated, the outer surface of the polymorphic aggregate is roughened, and the roughness of the surface of the polymorphic aggregate is increased; the adhesion of the aggregate surface is increased, which facilitates the subsequent adhesion of liquid recyclable materials to the surface of the polymorphic aggregate. (3) Aggregate preheating uses a stepped temperature rise to preheat polymorphic aggregates to prevent the aggregates from being directly preheated at high temperatures. Thermal expansion will occur during the preheating process, and cracks will be generated during the thermal expansion process, thus affecting the strength of the recyclable material wrapping. (4) The high-pressure gas nozzle of the granulation equipment is located below the chute mouth. The high-pressure gas nozzle is set obliquely upward, and high-pressure extremely cold gas is ejected obliquely upward from the bottom of the chute mouth. Increase the uniformity of the bonding of the recyclable material on the surface of the granular aggregate, increase the surface oxidation time, and increase stability.

[0025] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0026] The present invention provides a method for producing a new multi-morphological particle material, comprising the following steps:

[0027] S1: Preparation of polymorphic aggregate: crush the raw material with a crusher, sieve and sort the crushed aggregate to obtain granular aggregate, wash the granular aggregate with water and then dry it to obtain dried granular aggregate; remove impurities such as mud, dust and other impurities on the surface of the raw material to ensure the cleanliness of the polymorphic aggregate, and ensure the uniformity of the aggregate particles by sieving.

[0028] S2: Surface treatment of polymorphic aggregate: The surface of the dried polymorphic aggregate is treated to make the outer surface of the polymorphic aggregate rough, thereby increasing the roughness of the surface of the polymorphic aggregate; increasing the adhesion of the aggregate surface to facilitate the subsequent liquid recyclable material to adhere to the surface of the polymorphic aggregate.

[0029] S3: Preheating of polymorphic aggregate: preheat the dried granular aggregate obtained in S1 at 550℃-700℃ for 45min-65min to obtain preheated granular aggregate; preheat the aggregate first to prevent the aggregate from suddenly entering the high-temperature liquid recyclable material. The sudden exposure to heat will cause the aggregate to break, making it impossible to ensure the uniformity of the finished product particle size. At the same time, it will also affect the firmness of the produced product and make the finished product easy to break.

[0030] S4: Preparation of mixed liquid of recyclable materials and aggregates: transfer the recyclable materials to the slag tank, maintain the temperature of the recyclable materials at 1300℃-1450℃, add thermosetting adhesive to the slag tank, stir well, add the granular aggregate preheated in S2 to the slag tank, and continue to stir to disperse the aggregate into the liquid recyclable materials; after adding the thermosetting adhesive to the recyclable materials, stir well to make the liquid recyclable materials have a certain viscosity, add the aggregates and stir well to disperse the aggregates into the solution. The viscous liquid recyclable materials will more easily adhere to the outer surface of the aggregates.

[0031] S5: Granulation of mixed liquid: Pour the mixed liquid of recyclable materials and aggregates obtained in S3 into the chute of the granulation equipment, enter the granulation equipment through the chute, and blow extremely cold gas into the granulation equipment to promote the granulation of the mixed liquid to form multi-morphological particles; at this time, the multi-morphological particles include irregular aggregate particles wrapped with recyclable materials on the outside and spherical particles.

[0032] S6: Polymorphic particle sorting: sort the polymorphic particles obtained in S4, separate the polymorphic particles; separate spherical and non-spherical polymorphic particles. It is convenient to choose particles of different shapes according to needs, or when mixed, it can control the mixing ratio of spherical and irregular polymorphic particles.

[0033] S3 is a step-by-step heating method for preheating polymorphic aggregates. The specific steps for preheating polymorphic aggregates are as follows: (1) First, preheat the surface-treated polymorphic aggregates in S2 at 550-580°C for 20-25 minutes; (2) Increase the preheating temperature to 600-625°C and preheat the polymorphic aggregates at this temperature for 10-15 minutes; (3) Continue to increase the preheating temperature to 650-680°C and preheat the polymorphic aggregates at this temperature for 5-10 minutes; (4) Increase the preheating temperature to 690-700°C and preheat the polymorphic aggregates for 10-15 minutes. Use a step-by-step heating method to preheat polymorphic aggregates to prevent the aggregates from being directly preheated at high temperatures. Thermal expansion will occur during the heating process, and cracks will be generated during the thermal expansion process, thereby affecting the strength of the recyclable material wrapping.

[0034] S5: During the granulation process of the mixed liquid, a stirring device is set in the chute to continuously stir the liquid recyclable material in the chute. This allows the mixed liquid to be evenly mixed in the chute to prevent the polymorphic aggregates from sinking to the bottom and to prevent the particles from sticking together and blocking the chute.

[0035] In S5, the high-pressure gas nozzle of the granulation equipment is located below the chute mouth, and the high-pressure gas nozzle is set obliquely upward, and the high-pressure extremely cold gas is ejected obliquely upward from the bottom of the chute mouth. The raw material in S1 is ore or tailings. Generally, ores such as siderite or chalcopyrite with a higher specific gravity than recyclable materials are selected as raw materials. When the mixed liquid enters from the chute, the multi-morphological aggregates will generally sink gradually below. The high-pressure gas is blown obliquely upward, which can make the multi-morphological aggregates rotate and roll obliquely upward in the recyclable materials. The surface of the multi-morphological aggregates is in full contact with the recyclable materials, which is convenient for the surface of the multi-morphological aggregates to be wrapped with recyclable materials, improves the uniformity of the aggregate surface bonding to the recyclable materials, and increases the surface oxidation time and stability.

[0036] The screen used for screening in S1 is 4 mesh, 7 mesh, 15 mesh, 20 mesh or 30 mesh. It is convenient to select screens of different meshes according to the needs of different product particle sizes. Preferably, the aggregate in S1 can be screened twice in succession. First, it is filtered with a 4-mesh screen, and then the aggregate outside the screen is filtered with a 7-mesh screen. The aggregate in the 7-mesh screen is taken for standby use to ensure that the particle size of the aggregate is 3mm-5mm. Because the temperature of the liquid recyclable material is very high, these aggregates enter the liquid recyclable material, maintain a certain particle size and uniform particles, prevent the aggregate from directly melting at high temperature due to too small a particle size, and at the same time, the particle size of the product produced is relatively uniform.

[0037] In the slag pot in S3, 90-100 parts of liquid recyclable materials, 1-1.5 parts of thermosetting adhesives, and 120-150 parts of preheated aggregates need to be added, and the components are configured and stirred into a mixed liquid of aggregates.

[0038] S6: Polymorphic particle sorting: The polymorphic particles fall into the middle of the inclined conveyor belt, and a collection bucket is set at each end of the conveyor belt to separate spherical particles and non-spherical polymorphic particles.
