Description

Technical Field

[0001] The invention relates to the technical field of plastic recycling, in particular to a cleaning device based on plastic masterbatch recycling. Background Art

[0002] Plastic masterbatch, also known as masterbatch or masterparticle, is a concentrate made by loading an abnormal amount of plastic additives into the resin. When manufacturing plastic products, adding this masterbatch with an abnormal amount in proportion can replace the practice of directly adding various plastic additives. In the processing of existing plastic masterbatches, due to improper settings of equipment parameters such as temperature, pressure, and speed, some unqualified masterbatches will be produced. These masterbatches need to be recycled and reused, and in the process of recycling, cleaning equipment is needed to clean the surface of the unqualified masterbatch and separate the chemicals or impurities adhered to the surface of the masterbatch during transportation.

[0003] In the prior art, when cleaning the plastic masterbatch, it is necessary to first add an appropriate amount of cleaning liquid into the cleaning tank, then add the plastic masterbatch to be cleaned into the cleaning liquid, and use the stirring member in the cleaning tank to stir and clean the plastic masterbatch. Finally, the plastic masterbatch after cleaning is taken out of the cleaning tank through the conveying member and sent to the next process. The cleaning liquid will be replaced only after it is saturated after multiple cleanings. However, when the plastic masterbatch is cleaned frequently, the cleaning liquid will also be replaced frequently, resulting in the inability to clean the plastic masterbatch during the process of replacing the cleaning liquid, which will affect the cleaning efficiency of the plastic masterbatch. At the same time, frequent replacement of the cleaning liquid also increases the material cost and labor replacement cost.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0038] Embodiments of the present invention

[0039] Please refer to Figures 1 to 8 As shown:

[0040] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a cleaning device for recycling plastic masterbatch, including a cleaning box 1, a driving shaft 2 is rotatably connected between the inner walls of the cleaning box 1, one end of the driving shaft 2 is fixedly installed with the output end of the external driving motor, and a stirring blade 21 is equidistantly fixedly connected to the outer surface of the driving shaft 2, and one end of the driving shaft 2 passes through the cleaning box 1, and also includes: a cleaning liquid filtering circulation mechanism, an auxiliary stirring mechanism and an auxiliary filtering mechanism, and the auxiliary stirring mechanism and the auxiliary filtering mechanism are both driven by the cleaning liquid filtering circulation mechanism;

[0041] The cleaning liquid filtering circulation mechanism is used for circulating and filtering the cleaning liquid, the auxiliary stirring mechanism is used for improving the stirring effect of the stirring blade 21 on the plastic masterbatch, and the auxiliary filtering mechanism is used for improving the filtering effect of the cleaning liquid filtering circulation mechanism.

[0042] The cleaning liquid filtering circulation mechanism includes a filter box 301, which is fixedly connected to the bottom of the cleaning box 1, a card plate 302 is clamped on one side of the filter box 301, and a filter plate 303 is fixedly connected on one side of the card plate 302. The filter plate 303 consists of an inclined mesh filter plate and a transverse plate at the lower end. The inclined filter plate can filter the cleaning liquid, and the transverse plate can collect impurities blocked by the inclined plate. The filter plate 303 is located inside the filter box 301, and liquid inlet holes 304 are penetrated at the bottom of the cleaning box 1 and the top of the filter box 301. The filter box 301 and the cleaning box 1 are connected through the liquid inlet hole 304. A driving gear 305 is fixedly sleeved on the outer surface of the driving shaft 2, and a driven gear 306 is symmetrically rotated and connected to one side of the cleaning box 1, and the driving gear 305 is meshed with the driven gear 306.

[0043] One end of the driven gear 306 is fixedly connected to an eccentric block 307, and the outer surface of the eccentric block 307 is rotatably connected to a push-pull rod 308, one side of the cleaning box 1 is slidably connected to a slide rod 309, the slide rod 309 is rotatably connected to the push-pull rod 308, one side of the slide rod 309 is rotatably connected to a connecting rod 310, one side of the cleaning box 1 is symmetrically fixedly connected to a support frame 311, the bottom of the support frame 311 is fixedly connected to a T-shaped tube 312, the inner surface of the T-shaped tube 312 is slidably connected to a piston 313, one end of the piston 313 is fixedly connected to a push-pull column 314, and the push-pull column 314 is rotatably connected to the connecting rod 310.

[0044] A one-way liquid inlet valve is fixedly connected to the lower end of the T-shaped tube 312, a liquid extraction pipe 315 is fixedly connected to the lower end of the one-way liquid inlet valve, the lower end of the liquid extraction pipe 315 is fixedly connected to the top of the filter box 301, a one-way liquid outlet valve is fixedly connected to the upper end of the T-shaped tube 312, a liquid outlet pipe 316 is fixedly connected to the top of the one-way liquid outlet valve, and the liquid outlet pipe 316 is fixedly connected to one side of the cleaning box 1, and the diameter of the liquid inlet hole 304 is smaller than that of the plastic masterbatch, so the plastic masterbatch cannot enter the filter box 301 from the liquid inlet hole 304;

[0045] In the prior art, the cleaning liquid is replaced only after it has been saturated after multiple cleanings. However, when the plastic masterbatch is cleaned frequently, the cleaning liquid will also be replaced frequently, resulting in the equipment being unable to clean the plastic masterbatch due to the need to shut down during the replacement of the cleaning liquid, thereby affecting the cleaning efficiency of the plastic masterbatch. At the same time, frequent replacement of the cleaning liquid also increases material costs and labor replacement costs. Compared with the prior art, the implementation of this embodiment improves the fluidity of the cleaning liquid in the cleaning box 1, thereby accelerating the stripping of impurities on the outer surface of the plastic masterbatch in the cleaning box 1, and improving the cleaning efficiency. In addition, through the arrangement of the driving gear 305 and the driven gear 306, the circulation of the cleaning liquid can be achieved by the rotation of the driving shaft 2, thereby saving the installation of an additional driving source and reducing energy consumption.

[0046] For further examples, please refer to Figures 1 to 8 As shown:

[0047] The auxiliary stirring mechanism includes a connecting frame 401, which is fixedly connected to the outer surface of the push-pull column 314, and the connecting frame 401 is slidably connected to one side of the cleaning box 1. A toggle plate 402 is equidistantly slidably connected between the inner walls of the cleaning box 1, and protrusions 403 are equidistantly fixedly connected to the upper and lower sides of the toggle plate 402. A fixing rod 404 is fixedly connected between the toggle plates 402, and the connecting frame 401 is fixedly connected to the top of one of the toggle plates 402. The protrusion 403 is tilted. The tilted setting of the protrusion 403 can increase the range and angle of the plastic masterbatch when sliding.

[0048] The implementation of this embodiment further improves the cleaning efficiency of the masterbatch. At the same time, by moving the protrusion 403, the masterbatch can be prevented from gathering above the liquid inlet hole 304, thereby ensuring the stability of the circulating flow of the cleaning liquid.

[0049] For further examples, please refer to Figures 1 to 8 As shown:

[0050] The auxiliary stirring mechanism includes a fixed frame 501, which is fixedly connected to one side of the cleaning box 1. A sliding rod 502 is slidably connected to the top of the fixed frame 501, a fixed plate 503 is fixedly connected to the bottom of the sliding rod 502, a push block 504 is fixedly connected to one side of the sliding rod 502, a linkage shaft 505 is fixedly connected to one end of the driving shaft 2 close to the push block 504, a push rod 506 is fixedly connected to the outer surface of the linkage shaft 505, the push block 504 is located above the linkage shaft 505, a pressure rod 507 is equidistantly fixedly connected to the bottom of the fixed plate 503, the pressure rod 507 penetrates and is slidably connected to the top of the filter box 301, a spring 508 is equidistantly fixedly connected between the fixed plate 503 and the filter box 301, the bottom of the pressure rod 507 contacts the filter plate 303, and a roller is rotatably connected to the side of the push rod 506 away from the linkage shaft 505, so that when the push rod 506 contacts and pushes the push block 504, the friction between the push rod 506 and the push block 504 can be reduced through the rotation of the roller, thereby reducing the loss.

[0051] The implementation of this embodiment can shake off the impurities adhered to the filter plate 303, which not only prevents excessive accumulation of impurities and affects the filtering effect of the filter plate 303, but also increases the saturation time of the filter plate 303 and reduces the replacement frequency of the filter plate 303. At the same time, by shaking off the impurities on the surface of the filter plate 303, it also saves the time of subsequent staff in cleaning the filter plate 303, reduces labor costs, and further ensures the filtering effect of the cleaning liquid filtration circulation mechanism.

[0052] Everything in the above example works like this:

[0053] In the initial state: the spring 508 is in a normal state, the push rod 506 is not close to or in contact with the push block 504, and one end of the driving shaft 2 is fixedly mounted to the output end of the external driving motor.

[0054] The following is the working process of the cleaning liquid filtering circulation mechanism circulating the cleaning liquid:

[0055] When the plastic masterbatch is added to the cleaning box 1 for stirring and cleaning, the external driving motor is started, so that the driving shaft 2 is driven to rotate by the output end of the external driving motor, and the driving shaft 2 is driven to rotate by the driving gear 305. Because the driven gear 306 is meshed with the driving gear 305, when the driving gear 305 rotates, the driven gear 306 can be driven to rotate at the same time, and then the eccentric block 307 is driven to rotate through the driven gear 306, so that the eccentric block 307 pulls or pushes the push-pull rod 308, and then under the action of the push-pull rod 308, the sliding rod 309 can be driven to slide back and forth. In the process of the reciprocating sliding of the sliding rod 309, one end of the connecting rod 310 can be pushed or pulled, so that the other end of the connecting rod 310 pulls or pushes the push-pull column 314 and the piston 313 to slide back and forth, so that the piston 313 slides back and forth in the T-shaped tube 312. When the piston 313 moves in the direction away from the liquid extraction tube 315, The air pressure in the T-shaped tube 312 is reduced. Through the cooperation of the one-way liquid inlet valve and the one-way liquid outlet valve, the liquid extraction pipe 315 can suck the cleaning liquid in the filter box 301 into the T-shaped tube 312. When the piston 313 slides toward the liquid extraction pipe 315, the cleaning liquid can enter the liquid outlet pipe 316 from the T-shaped tube 312 again through the cooperation of the one-way liquid inlet valve and the one-way liquid outlet valve, thereby completing a cycle. During the cycle, the cleaning liquid and impurities enter the filter box 301 from the liquid inlet hole 304. Under the obstruction of the filter plate 303, the impurities are blocked to one side of the filter plate 303. Since the filter plate 303 is composed of a transverse plate and an inclined mesh plate, the impurities are blocked by the inclined mesh plate and will slide along the inclined surface to the upper surface of the transverse plate, so that when the card plate 302 is disassembled, the impurities can be carried out together, which improves the convenience of disassembly and cleaning, and saves the time of additional cleaning of impurities at the bottom of the filter box 301.

[0056] In addition, by allowing the cleaning liquid of the cleaning box 1 to enter the filter box 301, and then re-enter the cleaning box 1 after being filtered by the filter plate 303, the cleanliness of the cleaning liquid in the cleaning box 1 is improved, and the saturation time of the cleaning liquid is prolonged, thereby avoiding the operation of frequently replacing the cleaning liquid, improving the utilization rate of the cleaning liquid, and reducing the production cost. At the same time, by the cleaning liquid of the cleaning box 1 flowing to the filter box 301, the liquid outlet pipe 316 continuously sprays the cleaning liquid into the cleaning box 1, which can improve the fluidity of the cleaning liquid in the cleaning box 1, thereby accelerating the stripping of impurities on the outer surface of the plastic masterbatch in the cleaning box 1, and improving the cleaning efficiency. In addition, by setting the driving gear 305 and the driven gear 306, the circulation of the cleaning liquid can be achieved by the rotation of the driving shaft 2, thereby saving the installation of an additional driving source and reducing energy consumption.

[0057] Please refer to the above working process Figures 1 to 8 .

[0058] The following is the working process of the auxiliary stirring mechanism to improve the stirring effect of the stirring blade 21 on the plastic masterbatch:

[0059] Furthermore, when the cleaning liquid filtering circulation mechanism is in operation, the reciprocating movement of the push-pull column 314 can simultaneously drive the connecting frame 401 to slide back and forth, and then the connecting frame 401 can drive the toggle plate 402, the protrusion 403 and the fixing rod 404 to slide back and forth at the bottom of the cleaning box 1 at the same time. The inclined setting of the protrusion 403 can increase the range and angle of the plastic masterbatch to be toggled when the protrusion 403 slides, thereby further improving the cleaning efficiency of the masterbatch. At the same time, the toggle of the protrusion 403 can prevent the masterbatch from gathering above the liquid inlet hole 304, thereby ensuring the stability of the circulating flow of the cleaning liquid;

[0060] Please refer to the above working process Figures 1 to 8 .

[0061] The following is the working process of the auxiliary filtering mechanism to improve the filtering effect of the cleaning liquid filtering circulation mechanism:

[0062] Furthermore, when the driving shaft 2 rotates, the driving shaft 2 also drives the linkage shaft 505 to rotate, and the linkage shaft 505 drives the push rod 506 to rotate and approach the push block 504, thereby pushing the push block 504 to move upward, so that the push block 504 drives the sliding rod 502 to slide upward along the fixed frame 501, and the fixed plate 503 drives the pressure rod 507 to move upward, and the spring 508 is stretched. As the push rod 506 continues to rotate, the push rod 506 will stagger with the push block 504. At this time, under the rebound of the spring 508, the sliding rod 502, the fixed plate 503 and the pressure rod 507 will slide rapidly downward, thereby causing the pressure rod 507 to move upward. The rod 507 knocks on the upper surface of the filter plate 303, and the knocking can make the filter plate 303 vibrate, so that the impurities adhering to the filter plate 303 can be shaken off, which not only prevents the problem of excessive accumulation of impurities and affecting the filtering effect of the filter plate 303, but also keeps the filter plate 303 in a good working state, and also increases the saturation time of the filter plate 303, reduces the replacement frequency of the filter plate 303, and at the same time, by shaking off the impurities on the surface of the filter plate 303, it also saves the time of subsequent staff to clean the filter plate 303, reduces the labor cost, and further ensures the filtering effect of the cleaning liquid filtering circulation mechanism;

[0063] In addition, through the cooperation of the cleaning liquid filtering circulation mechanism, the auxiliary stirring mechanism and the auxiliary filtering mechanism, through the rotation of the driving shaft 2 in the prior art, the cleaning liquid filtering circulation mechanism, the auxiliary stirring mechanism and the auxiliary filtering mechanism can be operated simultaneously, so that when completing the cleaning liquid circulation filtration work, the auxiliary stirring of the cleaning liquid and the auxiliary cleaning of the filter net are completed at the same time, which not only improves the cleaning efficiency of the plastic masterbatch, but also improves the utilization rate of the kinetic energy generated during the stirring of the driving shaft 2, reduces the number of driving sources, makes the structure of the entire system simpler, reduces the cost and maintenance difficulty of the equipment, and at the same time reduces the time required to stop and switch other functions due to the completion of a single function, thereby improving the overall work efficiency.
