Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly particle cleaning technology, specifically a device for cleaning recycled environmentally friendly particle mixing. Background Technology

[0002] Recycled environmentally friendly pellets refer to granular products with specific shapes (mostly cylindrical, flat round, and sized) made from waste materials (such as plastics, rubber, metals, biomass, etc.) through a series of processing techniques such as recycling, crushing, washing, melting, and granulation. However, during the recycling process, recycled environmentally friendly pellets often have oil stains, dust, impurities, and residual pollutants attached to them, which directly affects the quality of subsequent processed products.

[0003] Referring to the patent document: Patent Publication No. CN118876282B, Patent Publication Date 2024-12-13, this invention specifically relates to a granule cleaning device for plastic recycling. The device includes a frame, an arc-shaped filter ring, friction components, a feeding mechanism, a water collection mechanism, a sensing mechanism, and a driving mechanism. The feeding mechanism includes a feeding hopper, a guide plate, and a first crossbar. The water collection mechanism includes a water tank and a water pipe. The sensing mechanism is used to cause the first crossbar to slide in the chute when the friction component moves along the axis of the arc-shaped filter ring, thereby causing the upper end of the guide plate to slide along the first crossbar. The driving mechanism is used to drive the friction component to rotate. This granule cleaning device for plastic recycling addresses the problems of existing friction cleaning machines where the material after friction cleaning of plastic granules is easily affected by wastewater, resulting in poor cleaning effect. Furthermore, when the friction chamber becomes blocked, although the chamber is expanded, the material is easily discharged directly, failing to achieve an effective cleaning effect.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found: Currently, when recycling and cleaning recycled environmentally friendly particles, they are usually directly put into a cleaning tank for a series of cleaning processes such as spraying and soaking. However, the particles are not dry-brushed before cleaning to remove dust and impurities adhering to their surface. This results in a large amount of water being consumed during cleaning, requiring longer cleaning steps to achieve a cleanliness level, leading to slow cleaning efficiency and serious resource waste.

[0005] Therefore, this utility model provides a recycled and environmentally friendly particle mixing and cleaning device. Utility Model Content

[0006] To address the problems of excessive water washing steps, high water consumption, and low efficiency caused by the lack of dry brush pretreatment in the existing recycling and cleaning of environmentally friendly granules, the purpose of this utility model is to provide a recycling and environmentally friendly granule mixing and cleaning device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a recycled environmentally friendly granule mixing and cleaning device, comprising a cleaning box, wherein two cleaning boxes are symmetrically distributed, and each of the two cleaning boxes is equipped with a cleaning mechanism at its upper part for cleaning the recycled environmentally friendly granules. The cleaning mechanism includes: The cleaning assembly includes a first cleaning roller rotatably mounted on one side of the middle of two cleaning boxes, and a second cleaning roller rotatably mounted on the other side of the two cleaning boxes. A drive gear is fixedly mounted on one side of each of the two first cleaning rollers, and a driven gear is fixedly mounted on one end of each of the two second cleaning rollers. The two driven gears are meshed with the drive gears. The two second cleaning rollers are connected by a transmission belt. A drive assembly is provided on one side of one of the first cleaning rollers. A vacuum cleaner is fixedly mounted on the top of the two cleaning boxes, and the two output ends of the vacuum cleaner are respectively connected to the two cleaning boxes. The screening component, located at the top of the cleaning box, is used to screen the recycled environmentally friendly particles.

[0008] Preferably, the screening assembly includes a screening box disposed on the upper part of the cleaning box. An inclined upper guide plate is detachably installed on the upper part of the screening box. The upper part of the upper guide plate has a plurality of evenly distributed screening holes. An inclined lower guide plate is detachably installed in the middle of the screening box, and the inclination direction of the lower guide plate is opposite to that of the upper guide plate. Two symmetrically distributed feeding boxes are fixedly installed on the lower part of the screening box. The lower parts of the two feeding boxes are fixedly installed in the middle of the top of the cleaning box. Feeding rollers are rotatably installed in the middle of the two feeding boxes.

[0009] Preferably, the drive assembly includes a drive motor fixedly installed in the middle of one side of the cleaning box, and one of the first cleaning rollers is fixedly installed in the middle of one side of the drive motor.

[0013] This invention provides a recycled and environmentally friendly particle mixing and washing device. Compared with the prior art, it has the following advantages: 1. This application uses a drive motor to drive the first cleaning roller to rotate. The drive gear and driven gear mesh with a gear ratio of 1:1.5, which drives the adjacent second cleaning roller to rotate in opposite directions at different speeds. This allows the two cleaning rollers to effectively rub and scrub the passing particles. The difference in rotation speed enhances the ability to peel off dust adhering to the surface of the particles. At the same time, the vacuum cleaner integrated on the top creates negative pressure in the cleaning area, which quickly sucks up and collects the dust. This achieves simultaneous cleaning and dust removal, making the pretreatment effect of this device significant and greatly reducing the load on the subsequent wet washing stage.

[0014] 2. This application, by setting up a screening channel composed of upper and lower guide plates with opposite inclination directions in the screening box, can separate mixed particles according to size, allowing particles of different sizes to enter different cleaning boxes for processing. This avoids cleaning dead corners caused by the mixing of particles of different sizes, ensuring uniform and thorough scrubbing. At the same time, the feeding box connected at the bottom and the rotating feeding roller inside the box that is in close contact with the box wall together form a sealed feeding mechanism. This mechanism can feed materials into the cleaning box at a uniform speed and in a controllable manner, and also plays a physical sealing role, effectively preventing dust generated during the cleaning process from overflowing, ensuring the cleanliness of the screening area and isolating the path of dust leakage to the outside.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a recycled environmentally friendly granule mixing and cleaning device, including a cleaning box 1, which has two symmetrically distributed cleaning boxes 1. Each of the two cleaning boxes 1 has a cleaning mechanism 2 on its upper part for cleaning the recycled environmentally friendly granules. The cleaning mechanism 2 includes: The cleaning assembly 21 includes a first cleaning roller 211 rotatably mounted on one side of the middle of two cleaning boxes 1, and a second cleaning roller 212 rotatably mounted on the other side of the two cleaning boxes 1. A drive gear 2111 is fixedly mounted on one side of each of the two first cleaning rollers 211, and a driven gear 2121 is fixedly mounted on one end of each of the two second cleaning rollers 212. Both driven gears 2121 are meshed with the drive gears 2111, and the gear ratio between the drive gear 2111 and the driven gear 2121 is 1:1.5. Therefore, the first cleaning roller 211... The rotation speed of the first cleaning roller 211 is different from that of the second cleaning roller 212, which enables the dry brushing of the recycled particles entering the cleaning box 1 to remove the dust attached to the surface of the particles. The two second cleaning rollers 212 are connected by a transmission belt. One of the first cleaning rollers 211 has a drive component on one side. The top of the two cleaning boxes 1 is fixedly installed with a vacuum cleaner 214. The two output ends of the vacuum cleaner 214 are respectively connected to the two cleaning boxes 1. When the vacuum cleaner 214 is started, the dust generated during cleaning can be sucked out from the cleaning box 1. The screening component 22 is located at the top of the cleaning box 1 and is used to screen the recycled environmentally friendly particles.

[0022] The screening assembly 22 includes a screening box 221 disposed on the upper part of the cleaning box 1. An inclined upper guide plate 222 is detachably installed on the upper part of the screening box 221. The upper guide plate 222 has a plurality of evenly distributed screening holes 2221. An inclined lower guide plate 223 is detachably installed in the middle of the screening box 221, and the inclination direction of the lower guide plate 223 is opposite to that of the upper guide plate 222. The upper guide plate 222 enables the screening and filtering of recycled particles. Large particles slide to one side as the upper guide plate 222 is inclined, while small particles fall onto the lower guide plate 223 through the screening holes 2221. As the lower guide plate 223 is inclined downwards, it slides down and enters the feed box 224. The screening process can separate larger particles from small particles. The screen box 221 is equipped with two symmetrically distributed feeding boxes 224 at the bottom. The bottom of each feeding box 224 is fixedly installed at the top center of the cleaning box 1. Feeding rollers 225 are rotatably installed in the middle of each feeding box 224. The outer side of each feeding roller 225 is in contact with the inner wall of the feeding box 224. The rotation of the feeding roller 225 evenly conveys the recycled granular material into the cleaning box 1 and ensures close contact with its inner wall. This prevents dust from entering the screen box 221 through the feeding box 224 and being discharged into the external environment.

[0023] The drive assembly includes a drive motor 213 fixedly installed in the middle of one side of the cleaning box 1. One of the first cleaning rollers 211 is fixedly installed in the middle of one side of the drive end of the drive motor 213. The drive motor 213 is a three-phase asynchronous motor of model Y132S-4. Driven by the drive motor 213, one of the first cleaning rollers 211 can be rotated. The first cleaning roller 211 and the second cleaning roller 212 are connected by the meshing of the driven gear 2121 and the driving gear 2111. The two second cleaning rollers are driven by the transmission belt, so that the first cleaning roller 212 and the second cleaning roller 211 in the two sets of cleaning assemblies 21 can rotate synchronously.

[0024] One end of one of the feeding rollers 225 is connected to the driven gear 2121 via a synchronous belt drive, and both feeding rollers 225 are connected via synchronous belt drives. The rotation of the driven gear 2121, under the drive of the synchronous belt, can drive the feeding roller 225 to rotate, and the two feeding rollers 225 can rotate synchronously under the drive of another synchronous belt.

[0025] A hopper 226 is fixedly installed at the top of the screening box 221. The hopper 226 has a conical structure that is wider at the top and narrower at the bottom. Its top is open to form a feed inlet, and its bottom opening is connected to the feed end of the screening box 221. It is used to guide and centrally transport the recycled environmentally friendly particles to be screened into the screening box 221. The lower part of each of the two cleaning boxes 1 is equipped with a corresponding cleaning device 3. Each of the two cleaning devices 3 integrates a rinsing device, a soaking device, and a drying device. The cleaning device 3 is used to remove surface dust, mud, and loose dirt from the recycled particles after dry brushing by soaking and rubbing, reducing the consumption of subsequent cleaning agents. The recycled particles are further cleaned by adding detergent at high temperature and mechanical friction. Then, the recycled particles are rinsed with clean water by the rinsing device to achieve the cleaning purpose. Finally, the moisture on the recycled particles is removed by the drying device.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] During operation, the mixture of recycled environmentally friendly granules to be processed is added into hopper 226. The conical structure of hopper 226 collects the material and guides it into screening box 221. The material first falls onto the inclined upper guide plate 222. Fine particles fall through the screening holes 2221 of the upper guide plate 222, while larger particles slide out to one side along the inclined surface of the upper guide plate 222, achieving preliminary screening and separation. Smaller particles that pass through the screening holes 2221 fall onto the lower guide plate 223, which is inclined in the opposite direction. The particles are fed up and slide down the slope, eventually entering the two feeding boxes 224 respectively. The feeding rollers 225 in the feeding boxes 224 rotate synchronously under the drive of the drive assembly. Since the outer wall of the rollers 225 is in close contact with the inner wall of the feeding boxes 224, an effective sealing and conveying mechanism is formed. The rotation of the feeding rollers 225 will evenly and quantitatively convey the recycled particles to the cleaning box 1 below, while preventing the dust generated during the cleaning process from escaping back through the feeding boxes 224 to the screening box 221 and entering the external environment. After the particles enter the cleaning box 1, the cleaning component 21 located in the middle is activated. The drive motor 213 drives one of the first cleaning rollers 211 to rotate. Through the meshing of the drive gear 2111 and the driven gear 2121 (the gear ratio is 1:1.5), the third cleaning roller 212 paired with the first cleaning roller 211 rotates relative to each other at different speeds. At the same time, the second cleaning rollers 212 in the two cleaning boxes 1 are connected by a transmission belt to achieve synchronous rotation of the first cleaning roller 211 and the second cleaning roller 212 in the two cleaning boxes 1. This effectively dry brushes and rubs the recycled particles passing between them, thereby removing the dry dust and loose dirt attached to the surface of the particles. During this process, the vacuum cleaner 214 is activated and continuously sucks the air in the cleaning box 1 through its suction port to promptly suck away and collect the dust generated by brushing, preparing for subsequent wet washing. Finally, the granules, after being dry-brushed, are discharged from the bottom of the cleaning box 1 and enter the corresponding cleaning equipment 3 below. In the soaking equipment, the granules are softened and the floating dust and sand are initially removed through soaking. Then, through rubbing and washing, the stubborn dirt is thoroughly removed by mechanical stirring or friction and the action of the cleaning agent. The granules are then rinsed with clean water by the rinsing equipment to thoroughly remove detergent residue and residual stains. Finally, the drying equipment removes the moisture from the surface of the cleaned granules, resulting in clean and dry recycled environmentally friendly granules.
