Description

Technical Field

[0001] This utility model belongs to the field of pyrolytic carbon black processing technology, and in particular relates to a pyrolytic granulation, drying, and grading equipment for carbon black. Background Technology

[0002] Waste tire pyrolysis is an irreversible thermochemical reaction that occurs under anaerobic or oxygen-deficient conditions, using high temperatures to decompose the organic matter in waste tires, releasing volatile products and forming solid coke. During incomplete thermal degradation, gaseous, liquid, and solid products can be formed. This method can completely decompose waste tires into useful products such as pyrolysis oil, pyrolysis carbon black, and pyrolysis non-condensable gases. Carbon black is the second largest product of tire pyrolysis. Pyrolysis carbon black is a product generated through pyrolysis technology; because it differs from traditional carbon black production methods, it is called pyrolysis carbon black.

[0003] The average particle size of pyrolytic carbon black is typically 40-50 nm, and its aggregates are similar to those of GPF carbon black. Because pyrolytic carbon black contains 14±2% ash and is primarily composed of silica, cobalt salts, and zinc compounds, it exhibits unique chemical and physical properties, with high crosslinking and diffusivity. However, existing pyrolytic carbon black grading devices often suffer from poor sieving performance and low sieving efficiency. Utility Model Content

It has the characteristics of good screening effect and high screening efficiency.

[0006] This utility model discloses a pyrolysis granulation drying carbon black grading equipment, comprising: a box body having a receiving cavity and a feed inlet communicating with the receiving cavity; a support connected to the outside of the box body via an elastic element and supporting the box body; a vibration motor connected to the box body and driving the box body to vibrate; and a screening assembly disposed in the receiving cavity and fixedly connected to the box body, including a first screening element and a second screening element arranged parallel to the first screening assembly, the first screening element being located above the second screening element, and the sieve holes of the first screening element being larger than the sieve holes of the second screening element; the first screening element having a first end and a feed inlet communicating with the first end.

[0007] In some embodiments, the screening assembly includes a coarse material screen, a medium material screen, and a fine powder screen arranged sequentially from top to bottom. The housing has outlets for receiving the oversize material from the coarse material screen, the medium material screen, and the fine powder screen, respectively, and an outlet for receiving the undersize material from the fine powder screen, respectively, is provided below the fine powder screen.

[0008] In some embodiments, the mesh diameter of the coarse material screen is 4.5-5.5 mm, the mesh diameter of the medium material screen is 3-4 mm, and the mesh diameter of the fine powder screen is 1.5-2.5 mm.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention provides a pyrolysis granulation and drying carbon black grading equipment. A vibrating motor vibrates the chamber, which in turn drives the screening components to vibrate, facilitating material dispersion and improving screening efficiency. Simultaneously, the multi-stage screen design ensures effective screening and achieves multi-stage classification of the pyrolysis carbon black. By limiting the inclination angle of the screening components to 1.3°-1.7°, it ensures that the pyrolysis carbon black is fully and effectively screened on each screening component. The oversize material is discharged from the receiving cavity through the outlet, while the undersize material is further screened by the next stage screening component or discharged from the receiving cavity. This also prevents poor screening results caused by excessively large inclination angles of the screening components, which would result in insufficient screening of the pyrolysis carbon black before it is discharged from the receiving cavity.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.

[0023] This utility model embodiment provides a pyrolysis granulation, drying, and grading equipment for carbon black. Figure 1 , 2This is a schematic diagram of the structure of a pyrolysis granulation drying carbon black grading equipment according to an embodiment of the present invention.

[0024] refer to Figure 1 , 2 As shown, the pyrolysis granulation drying carbon black grading equipment includes a housing 101, which has a receiving cavity and a feed inlet communicating with the receiving cavity. Furthermore, a feed inlet is vertically arranged on the top left side of the housing 101, and three sets of observation holes are evenly arranged from left to right for observing the operation inside the housing 101.

[0025] A pyrolysis granulation and drying carbon black grading device includes a support 102, which is connected to the outside of a housing 101 via an elastic element 105 and supports the housing 101. In some embodiments, the support 102 is an ear-type support 102, and the elastic element 105 is a spring. Further, three sets of ear-type supports 102 are respectively provided on the left and right sides of the housing 101, with six damping springs corresponding to each of the three sets of ear-type supports 102. The lower parts of the six damping springs correspond to six support frames for supporting the housing 101.

[0026] A pyrolysis granulation drying carbon black grading device includes a vibration motor 103, which is connected to a housing 101 and drives the housing 101 to vibrate. Furthermore, the vibration motor 103 is a high-frequency motor. Its working principle is to achieve material screening and grading through high-frequency vibration and grading technology. Its core working principle lies in causing the powder particles on each screening component to produce a "micro-jumping" phenomenon through vibration, effectively avoiding the problem of carbon black particles clogging the screen and significantly improving screening efficiency.

[0027] A pyrolysis granulation drying carbon black grading device includes a screening component, which is disposed in a receiving cavity and fixedly connected to a housing 101. The screening component includes a first screening element and a second screening element arranged parallel to the first screening component. The first screening element is located above the second screening element, and the sieve aperture of the first screening element is larger than that of the second screening element. The first screening element has a first end and a second end opposite to the first end. The second screening element has a third end corresponding to and located below the second end. The inlet of the housing 101 is disposed above the first end of the first screening element, and the housing 101 has a first outlet corresponding to the second end of the first screening element. The first screening element is inclined downwards from the first end to the second end at an angle of 1.3°-1.7°. The housing 101 has a second outlet corresponding to the third end of the second screening element, or the housing 101 has a second outlet corresponding to the third end of the second screening element and a third outlet corresponding to and below the third end of the second screening element.

[0028] The aforementioned pyrolysis granulation drying carbon black grading equipment utilizes a vibrating motor 103 to vibrate the housing 101, which in turn drives the screening components to vibrate. This facilitates material dispersion and improves screening efficiency. Simultaneously, the multi-stage screen setup ensures effective screening and achieves multi-stage classification of pyrolysis carbon black. By limiting the inclination angle of the screening components to 1.3°-1.7°, it ensures that the pyrolysis carbon black is fully and effectively screened on each screening component. The oversize material is discharged from the receiving cavity through the outlet, while the undersize material is further screened by the next stage screening component or discharged from the receiving cavity. This also prevents poor screening results caused by the pyrolysis carbon black being discharged from the receiving cavity without sufficient screening due to an excessively large inclination angle of the screening components.

[0029] In some embodiments, the screening assembly includes a coarse material screen 1041, a medium material screen 1042, and a fine powder screen 1043 arranged sequentially from top to bottom. The housing 101 has outlets corresponding to the coarse material screen 1041, the medium material screen 1042, and the fine powder screen 1043, providing accommodating chambers for the oversize material from the coarse material screen 1041, the medium material screen 1042, and the fine powder screen 1043. A discharge port corresponding to the undersize material from the fine powder screen 1043 is also provided below the fine powder screen 1043. In some embodiments, the mesh diameter of the coarse material screen 1041 is 4.5-5.5 mm, the mesh diameter of the medium material screen 1042 is 3-4 mm, and the mesh diameter of the fine powder screen 1043 is 1.5-2.5 mm. Furthermore, the coarse material screen 1041 has a mesh diameter of 5mm, the medium material screen 1042 has a mesh diameter of 3.5mm, and the fine powder screen 1043 has a mesh diameter of 2mm. Using multi-layer screens improves screening efficiency and processing capacity. The multi-layer screen design allows for the simultaneous processing of materials with different particle sizes, thereby increasing screening efficiency and production capacity. Additionally, the particle size requirement for pyrolytic carbon black is 0.5mm-2mm; using multi-stage screens further enhances the screening effect and efficiency.

[0030] In some embodiments, there are two vibrating motors 103, located at the bottom of the housing 101. The two vibrating motors 103 are symmetrically arranged on the left and right sides of the bottom of the housing 101, with their directions of rotation opposite. The main function of the vibrating motors 103 is to assist in the grading and screening of materials by generating high-frequency vibrations, with a frequency of 3000 times / minute or higher. This technical solution, by limiting the two vibrating motors 103 to be symmetrically arranged on the left and right sides of the bottom of the housing 101, and with their directions of rotation opposite, helps to counteract the horizontal excitation force and superimpose the vertical excitation force, ensuring the normal movement trajectory of the screen body and guaranteeing the screening effect.

[0031] Furthermore, the aforementioned pyrolysis granulation drying carbon black grading equipment uses a single housing 101 with multiple discharge ports for grading powders of various particle sizes. A vibrating motor 103 is installed at the bottom of the housing 101 using a hanging installation structure to meet the requirements of high-frequency vibration. In addition, the screen employs a multi-layer design, increasing its lifespan and preventing clogging and wear. Its structure is simple, maintenance is convenient, the failure rate is low, and it generates low noise and has a small dynamic load.

[0032] In some embodiments, the feed inlet of the pyrolysis granulation drying carbon black grading equipment is connected to the dryer 3 via a bucket elevator 2. The dryer 3 includes a kiln tail, the discharge port of which is connected to the pyrolysis granulation drying carbon black grading equipment via the bucket elevator 2, and a dust collector 4 is connected to the exhaust port of the kiln tail. In some embodiments, the dust collector 4 is connected to a fan 5.

[0033] The carbon black granules, after being granulated by the granulator, are discharged from the bottom of the granulator and then enter the dryer 3 through the kiln head feed inlet to dry the moisture. A hot air inlet is axially located on the left side of the kiln head of the dryer 3, and the hot air inlet flange is connected to the high-temperature flue gas output pipe of the hot air furnace. A driven gear ring is located on the left side of the dryer 3 cylinder, meshing with the driving gear on the transmission reducer to drive the dryer 3 clockwise. A safety guard with support rollers is located on the right side of the dryer 3, inside which are rear support rollers, which, together with the front support rollers, ensure the safe operation of the dryer 3.

[0034] A flue gas outlet is vertically installed at the upper part of the kiln tail on the right side of dryer 3, and is connected to cyclone dust collector 4 through a flue gas duct. The upper exhaust port of cyclone dust collector 4 is connected to the air inlet of flue gas dust collector 4, and the air outlet of dust collector 4 is connected to the air inlet of high-pressure blower 5. A dry material discharge port is installed at the lower part of the kiln tail on the right side of dryer 3, and is connected to the feed port of bucket elevator 2. The discharge port of bucket elevator 2 is connected to the feed port of housing 101.

[0035] The working process of the above-mentioned pyrolysis granulation drying carbon black grading equipment is as follows:

[0036] The dried pyrolytic carbon black is fed into the receiving cavity of the housing 101 through the feed inlet and falls onto the first screening element for screening. The oversize material obtained by the first screening element is discharged from the receiving cavity through the first discharge outlet, and the undersize material falls onto the second screening element for screening. The oversize material obtained by the second screening element is discharged from the receiving cavity through the second discharge outlet, and the undersize material is discharged from the receiving cavity or further screened. During this process, the vibration motor 103 drives the housing 101 to vibrate, thereby improving the screening efficiency.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
