Description

Technical Field

[0001] The present invention relates to the technical field of pigment waste grinding, and specifically relates to a solid waste recycling and treatment device. Background Art

[0002] In pigment production, there are a large amount of solid wastes. This part of the solid wastes can be roughly divided into solids such as iron oxide or titanium dioxide that still have utilization value and waste packaging materials or expired pigments that have no utilization value. Generally speaking, solid wastes that still have utilization value need to be preliminarily screened and ground before they can be used continuously.

[0003] The existing Chinese patent with the application number CN202410465651.1 discloses a grinding device for pigment processing, including a bracket. A plurality of upper and lower annular chucks are fixed at the center of the bracket. A corresponding plurality of grinding disc ring groups are arranged outside the annular chucks. A ring frame that rotates on the bracket is arranged outside the grinding disc ring groups. The present invention designs a novel grinding mechanism and an annular grinding disc adapted to this grinding structure. And to facilitate the collection of the ground pigment raw materials, the present invention divides the annular grinding disc into a plurality of combinable and detachable grinding disc ring group structures, and cooperates with an adjustment mechanism to adjust the umbrella-shaped grinding heads with different inclinations and different grinding states, and matches the annular grinding discs with different diameters, which can meet a variety of different grinding particle size requirements and the rough and fine processing work of pigment raw materials. The grinding head states in different forms are matched with the annular grinding discs with different layer heights and diameters, and are arranged and combined into a variety of grinding states, greatly enriching the applicable scope of the present device.

[0004] In the prior art, most of the wastes generated in pigment production that still have recycling value are titanium dioxide with a dry basis greater than 60% and some iron oxides. In the production process, this part of the wastes has different particle sizes and shapes, and has a certain hardness, and is accompanied by the characteristic of being relatively fragile. When recycling, it needs to be ground. However, due to the high brittleness of the wastes, the existing grinding devices have low grinding efficiency during grinding, and it is necessary to help improve the grinding efficiency.

Specific embodiments

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] The present invention will be further described below with reference to the embodiments. Embodiment 1

[0030] As Figures 1 to 3 shown, a solid waste recycling and treatment device includes a base 1, a driving component 2 and a crushing and rolling component 3. The driving component 2 is installed on the base 1, and the crushing and rolling component 3 is driven by the driving component 2. It is characterized in that the crushing and rolling component 3 includes a rotating cylinder 301 and a rolling ring 302 inside the rotating cylinder 301. The rolling ring 302 has a rotating shaft, and the rolling ring 302 is rotationally connected inside the rotating cylinder 301 through the rotating shaft;

[0031] Material leakage nets 309 are fixedly installed on the circumferential sides of the rotating cylinder 301 and the rolling ring 302. The rotating directions of the rotating cylinder 301 and the rolling ring 302 are opposite. A feeding cover 310 is provided on the side plate of the rotating cylinder 301. When feeding, waste materials are put into the inner diameter of the rolling ring 302 through the feeding cover 310.

[0032] Before feeding, it is necessary to open the feeding cover 310, then put in the waste materials to be crushed, such as carbon dioxide or iron oxide, etc., and then close the feeding cover 310. After the waste materials enter the feeding cover 310, they will fall into the rolling ring 302. Then, the driving component 2 is used to drive the rolling ring 302 and the rotating cylinder 301 to rotate synchronously. The rotating rolling ring 302 will drive the waste materials to continuously roll in the rolling ring 302. Under the centrifugal force of rotation, the waste materials will gradually stick to the inner diameter wall of the rolling ring 302 and rotate upward, and then fall from a higher position, colliding with the waste materials below. By using the collision between the waste materials, the waste material particles or waste material lumps are scattered. Under the rotating condition, the small broken waste material particles will fall between the rotating cylinder 301 and the rolling ring 302 through the leakage net 309 of the rolling ring 302. Since the rotating directions of the rotating cylinder 301 and the rolling ring 302 are opposite, the small waste material particles between the rotating cylinder 301 and the rolling ring 302 will be subjected to greater pressure and impact, which will intensify the friction between the small waste material particles and make the contact with the rotating cylinder 301 and the rolling ring 302 more sufficient. In this way, this part of the small waste material particles will be quickly rolled and crushed in the opposite rotating directions of the rotating cylinder 301 and the rolling ring 302, which can effectively and quickly improve the rolling efficiency and ensure the rolling effect. After rolling, the waste materials that meet the requirements will fall out from the leakage net 309 of the rotating cylinder 301 and can be collected later.

[0033] A plurality of fixed shafts are fixedly connected to the inner walls of the two side plates of the rotating cylinder 301, and the fixed shafts are rotatably connected with crushing plates 303 through torsion springs. The crushing plates 303 are located inside the rolling ring 302.

[0034] Since the rotating shaft of the rolling ring 302 is also located inside the rotating cylinder 301, the crushing plates 303 may interfere with the rotation of the part of the rotating shaft of the rolling ring 302 connected to the rotating cylinder 301. Therefore, the crushing plates 303 on the inner walls of the two side plates of the rotating cylinder 301 need to have a certain interval to accommodate the rotation of the part of the rotating shaft of the rolling ring 302 connected to the rolling ring 302. The waste materials in the rolling ring 302 will fall between the crushing plates 303 and the rolling ring 302 during the rotation of the rotating cylinder 301. Since the rotating directions of the rotating cylinder 301 and the rolling ring 302 are opposite, the crushing plates 303 fixed to the rotating cylinder 301 will rotate in the rotating direction of the rotating cylinder 301. However, different from the rolling action between the rotating cylinder 301 and the rolling ring 302, the connection between the crushing plates 303 and the rotating cylinder 301 is elastically supported by torsion springs, which is used to accommodate enough waste materials and help the waste materials concentrate and fully contact, and help the waste materials be quickly broken between the crushing plates 303 and the rotating cylinder 301 by using the opposite rotating directions of the two, so as to help improve the crushing speed.

[0035] Both inner walls of the two side plates of the rotating cylinder 301 are fixedly connected with a plurality of sleeves 304. A piston slide rod 305 is slidably connected in the sleeve 304. The end of the piston slide rod 305 is fixedly connected with a hammering block 306. The number of the hammering blocks 306 corresponds to the number of the crushing plates 303.

[0036] During the rotation, it is necessary to control the rotating speeds of the rotating cylinder 301 and the rolling ring 302 to be the same. In this way, when the hammering block 306 rotates to the directly below position, the crushing plate 303 will also rotate to the directly below position, and vice versa. When the hammering block 306 rotates to the highest position, under the action of its own gravity, the piston slide rod 305 will slide into the sleeve 304. At this time, the distance between the hammering block 306 and the crushing plate 303 is the largest. When the hammering block 306 gradually rotates to the lower part, the hammering block 306 will gradually extend outwards from the sleeve 304 under the action of centrifugal force and its own gravity until the piston slide rod 305 completely slides to the other end of the sleeve 304. At this time, the hammering block 306 will contact the crushing plate 303. In the rotating state, when the hammering block 306 rotates upwards, the hammering block 306 retracts. When the hammering block 306 rotates downwards, the hammering block 306 quickly extends outwards and hammers the crushing plate 303 that also rotates to the lower part at the same time. Under the rapid hammering of the hammering block 306, the waste material between the crushing plate 303 and the rolling ring 302 will be crushed, which helps the waste material to be quickly crushed and further helps to improve the crushing speed.

[0037] The top of the inner wall of the sleeve 304 is fixedly connected with a fixed magnet 307. The top of the piston slide rod 305 is fixedly connected with an attracting magnet 308. The fixed magnet 307 generates a magnetic attraction force on the attracting magnet 308.

[0038] When the hammering block 306 rotates to the highest point, the piston slide rod 305 and the hammering block 306 retract to the lowest point under the action of their own gravity. At this time, the fixed magnet 307 and the attracting magnet 308 are adsorbed together through magnetic attraction force. Along with the gradual downward rotation of the hammering block 306, at this time, the magnetic attraction force between the fixed magnet 307 and the attracting magnet 308 needs to overcome the gradually increasing gravity component of the piston slide rod 305 and the hammering block 306, as well as the centrifugal force generated during rotation. Then the time for the piston slide rod 305 to slide outwards will be delayed by the magnetic attraction force between the fixed magnet 307 and the attracting magnet 308, so that the moment when the hammering block 306 hammers the crushing plate 303 is delayed, making the moment when the hammering block 306 hammers closer to a sudden release, allowing the hammering block 306 to extend at a position closer to the directly below to make full use of the hammering effect of the hammering block 306, making the hammering moment of the hammering block 306 closer to the moment when the positions of the crushing plate 303 and the hammering block 306 coincide, ensuring that the hammering of the hammering block 306 on the crushing plate 303 can stably crush the waste material and ensuring the crushing effect. Embodiment 2

[0039] Based on the first embodiment, as Figures 3 to 5 shown,

[0040] the crushing plate 303 includes a limiting portion 3031 that extrudes the waste after being hammered by the hammering block 306 and a gathering portion 3032 that gathers the waste. The crushing plate 303 is integrally inclined. A trumpet-shaped space is formed between the inner diameter wall of the crushing plate 303 and the inner diameter wall of the rolling ring 302, and the large opening of the trumpet-shaped space faces the rotation direction of the rotating cylinder 301. The numbers of the crushing plate 303 and the hammering block 306 are both even.

[0041] During the rotation of the crushing plate 303 along with the rotating cylinder 301, since the gathering portion 3032 has a greater distance from the rolling ring 302, it can gather more waste. At the same time, the position of the waste is restricted by the limiting portion 3031 and cannot leave the space between the crushing plate 303 and the rolling ring 302. Meanwhile, since the numbers of the crushing plate 303 and the hammering block 306 are both even and the rotating speeds of the rotating cylinder 301 and the rolling ring 302 are the same, when one crushing plate 303 is at the upper position, there will be a hammering block 306 at the lower position hammering the crushing plate 303. And because the hammering block 306 in the rotation system of the rotating cylinder 301 will produce an effect similar to polarization, it will undoubtedly cause the overall device to generate a large vibration during operation. Due to the gathering of the gathering portion 3032 and the restriction of the limiting portion 3031, the crushing plate 303 will transfer more waste to directly above, corresponding to the hammering block 306 that is performing hammering work directly below, to balance the kinetic energy generated when the hammering block 306 hammers with the weight of the waste transferred to the upper part, playing the function and effect of a balance block, helping to reduce the vibration kinetic energy generated by the hammering block 306 to a certain extent. At the same time, after the gathering portion 3032 is hammered by the hammering block 306, the whole crushing plate 303 will rotate, and a part of the limiting portion 3031 will lift, allowing the broken small pieces of waste to burst out in the direction of the limiting portion 3031, enabling the broken waste to leave the restriction of the crushing plate 303, preventing the broken waste from being repeatedly broken, and enabling the broken waste to enter the space between the rotating cylinder 301 and the rolling ring 302 through the leakage net 309 of the rolling ring 302 for further rolling treatment.

[0042] Protrusions for grinding waste are provided on the inner diameter wall of the rotating cylinder 301, the outer diameter wall of the rolling ring 302, and the inner diameter wall of the rolling ring 302. The protrusions are used to help increase the contact with the waste. Embodiment Three

[0043] Based on the second embodiment, as Figure 2 、 Figures 5 to 6 shown,

[0044] The driving assembly 2 includes a main driving motor 201. The output end of the main driving motor 201 is fixedly connected with a driving bevel gear 202. Symmetrically distributed first driven bevel gears 203 and second driven bevel gears 204 are engaged with the driving bevel gear 202. The first driven bevel gear 203 is fixedly connected with the rotating shaft of the rolling ring 302. The second driven bevel gear 204 is fixedly connected to the outside of the rolling ring 302. The rotating shaft of the rolling ring 302 passes through the second driven bevel gear 204 and is rotatably connected to the two side plates of the rotating cylinder 301.

[0045] The main driving motor 201 serves as a power source. Through the driving bevel gear 202, it drives the first driven bevel gear 203 and the second driven bevel gear 204 to rotate together. Since the first driven bevel gear 203 and the second driven bevel gear 204 are symmetrically distributed on both sides of the driving bevel gear 202, during the rotation of the driving bevel gear 202, the rotation directions of the first driven bevel gear 203 and the second driven bevel gear 204 are opposite. At this time, only the first driven bevel gear 203 and the second driven bevel gear 204 with exactly the same parameters such as size and modulus are needed to control the rotating cylinder 301 and the rolling ring 302 to rotate in opposite directions and at the same rotational speed. At the same time, only by controlling the main driving motor 201 can the rotational speeds of the rotating cylinder 301 and the rolling ring 302 be controlled, and the control difficulty is low. Embodiment 4

[0046] On the basis of Embodiment 2, as Figure 8 shown,

[0047] The driving assembly 2 includes a first driving motor 205 and a second driving motor 206. The output end of the first driving motor 205 is fixedly connected with the rotating shaft of the rolling ring 302. The output end of the second driving motor 206 is fixedly connected with a driving gear 208. Tooth blocks 207 are circumferentially distributed on the circumferential outer wall of the rotating cylinder 301, and the tooth blocks 207 are engaged with the driving gear 208.

[0048] As the second implementation of the driving component 2, by connecting the rolling ring 302 to the first driving motor 205, the rotating cylinder 301 to the second driving motor 206, and a control program, it is possible to make the rotating speeds of the rotating cylinder 301 and the rolling ring 302 the same and the rotation directions opposite. Different from the first implementation of the driving component 2, the error of controlling the main driving motor 201 will increase to about twice the original due to the meshing of the first driven bevel gear 203 and the second driven bevel gear 204 and the interaction between the rotating cylinder 301 and the rolling ring 302. The separate control of the rolling ring 302 and the rotating cylinder 301 by the first driving motor 205 and the second driving motor 206 can not only more accurately control the rotating speeds of the rolling ring 302 and the rotating cylinder 301, but also, when the grinding requirement is not high, only turn on the second driving motor 206 to rotate the rotating cylinder 301, and the above-mentioned crushing and grinding work can also be completed, which can reduce the load required by the motors used.

[0049] When adjusting the rotating speed, the absolute value of the rotating speed difference between the rotating cylinder 301 and the rolling ring 302 is mainly adjusted. Under the conditions of the same rotating speed and opposite rotation directions, the absolute value of the rotating speed difference between the rotating cylinder 301 and the rolling ring 302 is twice the rotating speed provided by the main driving motor 201. When increasing the absolute value of the rotating speed difference, the main driving motor 201 needs to increase half of this absolute value, which undoubtedly increases the precision difficulty of adjusting the rotating speed. Using the dual-motor drive of the first driving motor 205 and the second driving motor 206 does not need to consider this problem. Therefore, the main driving motor 201 is suitable for use scenarios with low precision requirements, while the dual-motor drive of the first driving motor 205 and the second driving motor 206 is suitable for use scenarios with high precision requirements.

[0050] Working principle:

[0051] The waste material enters the rolling ring 302 through the feeding cover 310, and the driving component 2 drives the rotating cylinder 301 and the rolling ring 302 to rotate in opposite directions together. The waste material inside the rolling ring 302 contacts the crushing plate 303. Under the centrifugal force, the hammering block 306 hammers the crushing plate 303 near the lowest point position, so that the waste material between the crushing plate 303 and the rolling ring 302 is crushed. Along with the opposite rotation of the crushing plate 303 and the rolling ring 302, the crushed waste material quickly spreads out and falls from the leakage mesh 309 on the rolling ring 302 to between the rotating cylinder 301 and the rolling ring 302. Using the opposite rotation between the rotating cylinder 301 and the rolling ring 302, the waste material is quickly rolled until the size conforms to the leakage mesh 309 on the rotating cylinder 301, and then falls out from the leakage mesh 309 of the rotating cylinder 301, completing the rapid work of crushing and rolling and improving the rolling efficiency.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
