Description

Technical Field

[0001] This utility model relates to the field of color masterbatch production technology, and more specifically, to a color masterbatch production water washing device. Background Technology

[0002] Color masterbatch is a high-concentration colorant made by uniformly dispersing an extraordinary amount of pigment or dye in a carrier resin. It is widely used in the coloring process of plastic products. In the production process of color masterbatch, after granulation, it is usually necessary to wash it with water to remove residual oil, mold release agent, dust and other impurities on the surface of the granules, so as to ensure the cleanliness, color uniformity and subsequent processing performance of the product.

[0003] Existing masterbatch washing equipment mostly employs simple soaking or spraying methods, resulting in low cleaning efficiency and problems such as incomplete cleaning, water waste, and low automation. Specifically, traditional soaking methods often require a long time to achieve a good cleaning effect, while spraying, although faster, can easily create blind spots, leading to some particles not being thoroughly cleaned. Furthermore, traditional washing systems generally lack water filtration and recycling capabilities, resulting in the direct discharge of large amounts of wastewater, which not only increases production costs but also creates environmental pressure. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a water washing device for color masterbatch production to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A masterbatch production washing device includes a washing tank with a guide plate inside. A baffle plate is provided between the bottom of the guide plate and the washing tank, and the baffle plate is slidably connected to the washing tank. One side of the baffle plate is connected to a pull plate, and one side of the pull plate is connected to an electric telescopic rod. A stirring mechanism is provided above the guide plate, and a rinsing mechanism is provided below the guide plate. The rinsing mechanism includes an installation plate inside the washing tank, a rinsing pipe connected below the installation plate, a rinsing pipe connected to a connecting pipe, multiple rinsing nozzles connected to the rinsing pipe, and a filter inclined plate below the rinsing pipe, which is connected to the washing tank.

[0007] Furthermore, an opening is provided on one side of the deflector plate, which matches the baffle plate, and an electric telescopic rod is installed above the mounting plate.

[0008] Furthermore, the stirring mechanism includes a central shaft located above the guide plate, a stirring rod connected to the central shaft, one end of the central shaft being connected to the washing tank via a bearing, and the other end passing through the washing tank and connected to the drive motor, which is fixed to the outside of the washing tank.

[0009] Furthermore, the bottom of the washing tank is provided with two fixing slots, and a filter plate and an activated carbon plate are slidably connected inside the two fixing slots respectively. One end of the filter plate and the activated carbon plate passes through the washing tank and is connected to the fixing plate.

[0010] Furthermore, a support column is provided above the fixed plate. The support column is rotatably connected to the washing tank. One end of the support column is connected to the fixed block. A screw is threaded inside the fixed block. One end of the screw is connected to the abutment plate, and the other end of the screw is connected to the rotating plate.

[0011] Furthermore, a recycling pipe is connected to the bottom of the washing tank, one end of which is connected to the recycling tank. The top of the recycling tank is connected to the water pump via a water suction pipe, and the output end of the water pump is connected to the washing tank via a water inlet pipe.

[0012] Furthermore, the recycling bin is located on one side of the washing bin.

[0013] Furthermore, the washing tank has an inlet at the top and a discharge outlet on one side of the filter plate.

[0014] The beneficial effects of this utility model are as follows:

[0025] 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.

[0026] According to an embodiment of the present invention, a washing apparatus for producing color masterbatch is provided.

[0027] like Figures 1-5As shown, the masterbatch production washing device according to an embodiment of the present invention includes a washing tank 1. A guide plate 2 is provided inside the washing tank 1. The guide plate 2 is arranged at an angle, with one end fixed to the side wall of the washing tank 1 and the other end extending downwards to the bottom area. A baffle plate 3 is provided between the bottom end of the guide plate 2 and the washing tank 1. The baffle plate 3 is slidably connected to a groove on the side wall of the washing tank 1 in a horizontal direction, and can block the discharge channel below the guide plate 2 in a closed state, achieving sealing and liquid retention during the washing process. After washing is completed, the baffle plate 3 can be opened in a controlled manner. One side is connected to the pull plate 4, and the pull plate 4 is connected to the electric telescopic rod 5 on one side. An opening 8 is provided on one side of the guide plate 2, which matches the baffle plate 3. A stirring mechanism 6 is provided above the guide plate 2. The stirring mechanism 6 includes a central shaft 601 located above the guide plate 2, and a stirring rod 602 connected to the central shaft 601. The stirring rod 602 can generate strong turbulence and shear force during rotation, promoting mutual friction between the masterbatch particles and full contact with the cleaning liquid, effectively removing contaminants such as oil, release agent, and dust adhering to the surface. One end of 601 is connected to the washing tank 1 via a bearing, and the other end passes through the washing tank 1 and is connected to the drive motor 603. The drive motor 603 is fixed to the outside of the washing tank 1. The speed of the drive motor 603 can be adjusted by a frequency converter to adapt to the cleaning needs of different types of masterbatches. A rinsing mechanism 7 is provided below the guide plate 2. The rinsing mechanism 7 includes a mounting plate 701 connected inside the washing tank 1. A rinsing pipe 702 is connected below the mounting plate 701. The rinsing pipe 702 is connected to an external water supply system via a connecting pipe 703. The water supply system can provide clean water for rinsing. Multiple rinsing nozzles 704 are connected to the pipe 702 (only one row is shown in the figure, but multiple rows can be installed as needed in actual use). A filter inclined plate 705 is provided below the rinsing pipe 702. The filter inclined plate 705 is connected to the water washing tank 1. A discharge port 23 is provided on one side of the filter inclined plate 705. Several filter holes or gaps are provided on the surface of the filter inclined plate 705 to allow the washing water to pass through smoothly and be discharged downwards. The washed masterbatch slides along the inclined surface to the discharge port 23 on one side to achieve preliminary solid-liquid separation. The electric telescopic rod 5 is installed above the mounting plate 701.

[0028] like Figures 1-5As shown, the bottom of the washing tank 1 has two fixed grooves 9, and a filter plate 10 and an activated carbon plate 11 are slidably connected inside the two fixed grooves 9 respectively. The filter plate 10 is a stainless steel woven mesh or a perforated plate, and the pore size can be selected according to actual needs (such as 80~200 mesh) to intercept fine plastic particles, dust and other solid impurities suspended in the water. The activated carbon plate 11 is filled with coconut shell activated carbon or other high adsorption materials to adsorb oil stains, organic dye molecules, odor substances and other substances dissolved in the washing water. One end of the filter plate 10 and the activated carbon plate 11 passes through the washing tank 1 and is connected to the fixed plate 12. A support column 13 is provided above the fixed plate 12. The support column 13 is rotatably connected to the washing tank 1. One end of the support column 13 is connected to the fixed block 14. A screw 15 is threaded inside the fixed block 14. One end of the screw 15 is connected to the abutment. The connecting plate 16 is connected to the other end of the screw 15, which is connected to the rotating plate 17. Rotating the rotating plate 17 can drive the screw 15 to move axially, pushing the end of the connecting plate 16 to press the ends of the filter plate 10 and the activated carbon plate 11, thus achieving quick locking and sealing. The bottom of the washing tank 1 is connected to the recovery pipe 18, which is equipped with a one-way valve. One end of the recovery pipe 18 is connected to the recovery box 19, which is equipped with a water inlet. The bottom of the recovery box 19 is connected to the drain pipe for periodically changing the water quality. The top of the recovery box 19 is connected to the water pump 21 through the water pump pipe 20. The output end of the water pump 21 is connected to the washing tank 1 through the water inlet pipe. The recovery box 19 is located on one side of the washing tank 1. The top of the washing tank 1 is equipped with a feed port 22 for feeding in the wet masterbatch after granulation. The feed port 22 can be equipped with a cover to prevent water splashing.

[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0030] In actual use, the operator first opens the inlet 22 cover at the top of the washing tank 1 and puts the wet masterbatch, which contains oil and release agent after granulation, into the washing tank 1. Then, the inlet 22 is closed, and an appropriate amount of cleaning water is injected into the washing tank 1 through the external water supply system. The water level can be adjusted according to the amount of material to ensure that the masterbatch is completely submerged. Then, the drive motor 603 is started, which drives the central shaft 601 and the stirring rod 602 to rotate. During rotation, the stirring rod 602 generates strong turbulence and shear force, causing sufficient friction between the masterbatch particles. Simultaneously, the water flow continuously washes the particle surface, effectively removing the attached oil, release agent, dust, and other impurities, achieving preliminary and efficient cleaning. During the cleaning process, the baffle plate 3 below the guide plate 2 is in a closed state. When cleaning is complete, the drive motor 603 stops running, and the stirring mechanism 6 stops working. At this point, by activating the electric telescopic rod 5, it retracts, causing the pull plate 4 to move horizontally to one side, thereby pulling the baffle plate 3 out of the opening 8 of the guide plate 2, thus opening the discharge channel. The cleaned masterbatch slides down the guide plate 2 under gravity and enters the rinsing mechanism 7 area. During the material's descent, the external water supply system continuously supplies water to the rinsing pipe 702 through the connecting pipe 703. The water flows through multiple rinsing nozzles 704 to perform a comprehensive secondary rinse on the masterbatch, further removing residual contaminants and significantly improving product cleanliness. After being rinsed by the spray, the masterbatch continues to slide down the guide plate 2 to the lower filter inclined plate 705. The surface of the filter inclined plate 705 has several filter holes or gaps, allowing the cleaning wastewater to pass smoothly and flow downwards into the bottom area of ​​the washing tank 1. The clean masterbatch, because its particle size is larger than the filter hole size, cannot pass through and slides along the inclined surface to the discharge port 23 on one side, achieving preliminary solid-liquid separation. The discharge port 23 can be connected to the drying equipment or temporary storage container in the next process to complete the material conveying. Meanwhile, the cleaning wastewater containing fine particles and oil collects at the bottom of the washing tank 1 under gravity. It is filtered by the filter plate 10 and activated carbon plate 11 and discharged through the recovery pipe 18 connected to the bottom. A one-way valve is installed on the recovery pipe 18 to prevent backflow of external impurities and ensure safe system operation. The wastewater flows through the recovery pipe 18 into the recovery tank 19 located on one side of the washing tank 1, and is temporarily stored inside the tank through the inlet. By starting the water pump 21, relatively clean water from the upper layer is drawn from the recovery tank 19 through the suction pipe 20 and pumped back to the washing tank 1 through the inlet pipe for use in the next batch of cleaning or as a water source for the rinsing mechanism 7, forming a closed-loop water circulation system. To ensure that the filter components do not loosen due to water pressure during operation, a fixing plate 12 is provided on the outside of the filter plate 10 and activated carbon plate 11, with a support column 13 installed above it. The support column 13 is rotatably connected to the washing tank 1.By rotating the rotating plate 17, the screw 15 is driven by the threaded transmission within the fixed block 14, pushing the abutment plate 16 forward to press the ends of the filter plate 10 and the activated carbon plate 11, achieving quick locking and reliable sealing. When the filter plate 10 and the activated carbon plate 11 need to be replaced, the screw 15 can be rotated in the opposite direction to release the fixation of the filter plate 10 and the activated carbon plate 11, and then the support column 13 can be rotated to remove the filter plate 10 and the activated carbon plate 11 from the inside of the washing tank 1.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
