Technical Field
[0001] This utility model relates to the field of engineering plastics processing technology, and in particular to a raw material cleaning device for engineering plastics processing. Background Technology
[0002] There are two types of raw materials used in the production of engineering plastics. One type is virgin raw material granules, which can be used directly in the production and processing of engineering plastics. The other type is recycled waste engineering plastics, which require deep cleaning to ensure that the granules produced meet processing standards. The cleaning method involves rubbing the crushed plastic blocks with hot water and detergent, followed by further cleaning in a rinsing tank.
[0003] The above-mentioned cleaning process is usually carried out in separate equipment. After the rough washing, the plastic fragments need to be transferred back to the fine washing container as a whole, which greatly reduces the cleaning efficiency of the raw materials.
[0004] To address the aforementioned issues, a raw material cleaning device for engineering plastics processing is proposed. Utility Model Content
[0005] The main purpose of this invention is to provide a cleaning device for engineering plastic processing raw materials, which solves the problems mentioned in the background art.
[0006] The objective of this utility model can be achieved by adopting the following technical solution: A cleaning device for engineering plastic processing raw materials includes a box base, on both sides of the top of the box base, cleaning mechanisms are symmetrically fixed, and a shut-off mechanism is installed between the cleaning mechanisms. The cleaning mechanism includes a coarse washing component and a rinsing component. Both the coarse washing component and the rinsing component consist of a perforated cleaning tank and a sealing cover. The perforated cleaning tank is rotatably connected inside the sealing cover, and a power unit is also installed on the outside of the perforated cleaning tank. The shut-off mechanism includes a connecting cover fixed to the sealing cover, a shut-off plate slidably and sealingly connected inside the connecting cover, a lifting screw threadedly connected to the ear plate on one side of the top of the shut-off plate, and a first motor connected to the bottom end of the lifting screw.
[0007] Furthermore, the housing is divided into a coarse washing pool and a rinsing pool by a partition, and the bottom opening groove of the sealing cover is sealed and connected to the coarse washing pool and the rinsing pool respectively.
[0008] Furthermore, the power unit includes a gear ring and a wheel rail fixedly sleeved at both ends of the outside of the hollow cleaning tank. Gears mesh on both sides of the bottom of the gear ring, and a support wheel slides within the wheel rail. Both the gears and the support wheel are rotatably mounted to the top of the tank base via a bracket.
[0009] Furthermore, a second motor fixed to the top of the housing is installed on one side of the gear. A drive shaft is rotatably mounted on the top of the housing directly below the second motor. Synchronous belts are sleeved on both ends of the drive shaft. One end of the synchronous belt is sleeved on the output shaft of the second motor, and the other end is sleeved on the gear on one side of the rinsing assembly.
[0010] Furthermore, a support rod is mounted on the top end of the lifting screw via a bearing, and the bottom of the support rod and the bottom of the first motor are both fixed to the top of the sealing cover by bolts.
[0011] Furthermore, the inner bottom of the connecting cover is rotatably connected to a flip base via a pivot pin, and the bottom of the flip base is hinged to an electric push rod, the bottom of which is fixed to the top of the housing.
[0012] Furthermore, both the coarse washing assembly and the rinsing assembly have hinged door panels installed on their outer sides, a discharge plate is provided directly below the output end of the rinsing assembly, and a reamer is welded into the inner wall of the hollowed-out cleaning tank.

[0017] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.
[0018] like Figures 1-8As shown in the figure, this embodiment provides an engineering plastic processing raw material cleaning device, including a box base 1. Cleaning mechanisms 2 are symmetrically fixed on both sides of the top of the box base 1, and a shut-off mechanism 3 is installed between the cleaning mechanisms 2. The cleaning mechanism 2 includes a coarse washing component 201 and a rinsing component 202. Both the coarse washing component 201 and the rinsing component 202 are composed of a hollow cleaning tank 208 and a sealing cover 206. The hollow cleaning tank 208 is rotatably connected inside the sealing cover 206, and a power unit 4 is also installed on the outside of the hollow cleaning tank 208. The shut-off mechanism 3 includes a connecting cover 304 fixed between the sealing cover 206 and the connecting cover 304. A shut-off plate 301 is slidably and sealingly connected inside the connecting cover 304. A lifting screw 303 is threadedly connected to the ear plate on one side of the top of the shut-off plate 301, and a first motor 305 is connected to one end of the bottom of the lifting screw 303.
[0019] The housing 1 is divided into a coarse washing pool 101 and a rinsing pool 102 by a partition. The bottom opening groove of the sealing cover 206 is sealed and connected to the coarse washing pool 101 and the rinsing pool 102 respectively.
[0020] In the above structure, the bottom of the perforated cleaning tank 208 is in contact with the inner wall of the sealing cover 206. After the cleaning liquid enters, the resistance of the raw material and the resistance of the tank can keep a portion of the cleaning liquid buffered in the tank, thus achieving the effect of soaking the raw material. The advantage of this method is that it satisfies the purpose of traditional soaking and friction cleaning, and the cleaning liquid is filtered by the filter screen 103 during circulation, thereby improving the cleaning effect of the cleaning liquid and avoiding the problem that in the traditional method, all the cleaning liquid is always soaking the raw material and cannot be treated.
[0021] The power unit 4 includes a gear ring 402 and a wheel rail 405 fixedly sleeved on both ends of the outside of the hollow cleaning tank 208. Gears 401 mesh on both sides of the bottom of the gear ring 402. A support wheel 404 is slidably limited inside the wheel rail 405. Both the gears 401 and the support wheel 404 are rotatably mounted to the top of the tank base 1 through a bracket.
[0022] In the above structure, gears 401 are provided on both sets of hollow cleaning tanks 208, wherein the hollow cleaning tank 208 located in the coarse washing component 201 is a driving gear, and the hollow cleaning tank 208 located in the rinsing component 202 is a driven gear.
[0023] A second motor 403, fixed to the top of the housing 1, is fitted to one side of the gear 401. A transmission shaft 406, rotatably mounted to the top of the housing 1, is located directly below the second motor 403. Synchronous belts 407 are fitted at both ends of the transmission shaft 406. One end of the synchronous belt 407 is fitted on the output shaft of the second motor 403, and the other end is fitted on the gear 401 on one side of the rinsing assembly 202.
[0024] In the above structure, a speed reducer is provided on the output of the second motor 403, which can output power after speed reduction to drive the hollow cleaning tank 208 to rotate at a speed of 15 revolutions / min.
[0025] The top end of the lifting screw 303 is fitted with a support rod 302 via a bearing. The bottom of the support rod 302 and the bottom of the first motor 305 are both fixed to the top of the sealing cover 206 by bolts. The inner bottom of the connecting cover 304 is rotatably connected to a flip base 304b via a pivot pin. The bottom of the flip base 304b is hinged to an electric push rod 304a. The bottom of the electric push rod 304a is fixed to the top of the housing 1. The gap between the flip base 304b and the connecting cover 304 allows the dripping cleaning fluid to flow back into the coarse washing water tank 101 through the strainer at the top of the housing 1.
[0026] In the above structure, the lifting screw 303 is controlled by the control panel set on the outer wall of the sealing cover 206 and the first motor 305 is manually operated by visual inspection. The flipping base 304b can be flipped and tilted by the electric push rod 304a, so that when the coarse washing component 201 conveys the cleaning material into the rinsing component 202, the residual material can slide into the coarse washing component 201, avoiding obstruction of the falling action of the connecting cover 304.
[0027] Both the coarse washing assembly 201 and the rinsing assembly 202 have hinged door panels 6 installed on their outer sides. The inner side of the door panels 6 is rotatably connected to the end of the hollow washing tank 208. A discharge plate 5 is provided directly below the output end of the rinsing assembly 202. A reamer 207 is welded into the inner wall of the hollow washing tank 208. The reamer 207 is configured in the same way as the spiral blades in a common cement mixing tank. Forward rotation is the mixing mode, and reverse rotation is the discharge mode. The first motor 305 and the second motor 403 are both servo motors, which can be started, stopped and controlled in both directions in real time through the onboard control panel.
[0028] The top of the sealing cover 206 is also fixed with a water distribution tank 204 that is interconnected with each other. A water pump assembly 205 is fixed on the top of the water distribution tank 204. A return pipe 203 that passes through the water distribution tank 204 is connected to the input end of the water pump assembly 205. The bottom of the return pipe 203 is connected to the interior of the coarse washing water tank 101 and the rinsing water tank 102. A filter screen 103 embedded in the tank base 1 is provided at the connection point. The filter screen 103 is used to filter large particles of debris.
[0029] In the above structure, the water distribution tank 204 is set into two sets. One set is filled with a mixture of hot water and detergent for cleaning the coarse washing component 201, and the other set is filled with clean water for rinsing.
[0030] The working principle of this device is as follows: This device is designed for cleaning crushed and recycled engineering plastics. During operation, it is connected to an external power source, and the control panel on the outer wall of the sealed cover 206 controls the start and stop of each electrical component. Operation is performed manually and visually.
[0031] Open the door panel 6 on one side of the perforated cleaning tank 208 in the coarse washing assembly 201. Feed the plastic fragments into the coarse washing assembly 201 through the feeding device. At this time, the stop plate 301 is in the stop state. The mixture of 70° hot water and cleaning agent in the water distribution tank 204 enters the sealing cover 206 through the bottom hole, covers the raw material and drains into the coarse washing pool. Start the second motor 403 to drive the gear 401 to drive the gear ring 402 to rotate, which in turn drives the perforated cleaning tank 208 to rotate. The reamer 207 stirs the raw material and cleans the plastic pieces by friction. The water pump assembly 205 draws the cleaning liquid into the water distribution tank 204 through the return pipe 203 for circulation. After the coarse washing set time is over, stop the liquid feeding.
[0032] After the plastic block is completely drained of the cleaning liquid, the first motor 305 is started to drive the lifting screw 303 to rotate, raising the stop plate 301 from the connecting cover 304. The second motor 403 drives the hollow cleaning tank 208 to rotate in the opposite direction. The reamer 207 pushes the raw material through the connecting cover 304 and into the hollow cleaning tank 208 of the rinsing assembly 202.
[0033] Synchronously, the drive shaft 406, through the transmission of the synchronous belt 407, drives the hollow cleaning tank 208 of the rinsing assembly 202 to rotate in the opposite direction. The reamer 207 is in discharge mode. After the raw material enters the tank evenly, it moves towards the discharge end. After discharge, the electric push rod 304a lifts and flips the base 304b, tilting and sliding the remaining raw material into the tank of the rinsing assembly 202 to empty the area above the flipping base 304b. The stop plate 301 is lowered, and the door cover 6 of the rinsing assembly 202 is closed. The second motor 403 rotates forward again, and the water distribution tank 204 adds clean water to start rinsing. At this time, the reamer 207 is in stirring mode, and raw materials to be cleaned can continue to be added to the coarse washing assembly 201, thus achieving continuous operation.
[0034] After rinsing, the discharge gate cover 6 is opened, the second motor 403 reverses, and the stop plate 301 continues to remain closed. After the rinsed raw material is completely discharged from the tank, the stop plate 301 is raised, and the raw material to be rinsed is sent into the rinsing tank to prevent contamination of the clean raw material after cleaning.
[0035] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
