Description

Technical Field

[0001] This utility model relates to the technical field of resin cleaning equipment, and specifically to a resin cleaning device. Background Technology

[0002] Existing cleaning equipment has structural design flaws. For example, the lack of a proper connection between the water storage container and the cleaning container leads to an unstable supply of cleaning fluid, making it impossible to guarantee continuous and efficient cleaning operations. The cover design of the cleaning container is also unreasonable, making it inconvenient to open and affecting the pouring of the resin to be cleaned, thus reducing operational convenience. Furthermore, the improper placement of the water outlet and inlet on the tank results in uneven flow of the cleaning fluid within the tank, easily leading to incomplete cleaning and a large amount of residual impurities in the resin after cleaning, failing to meet production requirements.

[0003] Regarding the agitation device, existing technologies also have shortcomings. The agitator blades have a simple structure, usually a single layer, resulting in a limited agitation range. This makes it impossible to thoroughly clean the resin in different locations within the tank, leading to significant differences in cleaning effectiveness between upper and lower layers, creating cleaning dead zones, and greatly impacting overall cleaning efficiency. Furthermore, it is difficult to ensure the coaxiality of the drive and agitation components, which can easily generate significant vibration and noise during operation. This not only affects the stability and lifespan of the equipment but may also interfere with the surrounding working environment.

[0004] Furthermore, existing cleaning devices also have problems in the discharge stage. The bottom of the tank is mostly flat, and the discharge port is located at the edge, making it easy for the cleaned resin to accumulate in the corners of the tank, resulting in incomplete discharge and requiring manual cleaning, which increases labor intensity and production costs. These problems severely restrict the efficient implementation of resin cleaning work, and a new resin cleaning device is urgently needed to solve them. Utility Model Content

[0025] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0026] In this embodiment of the invention, the terms "system" and "network" are used interchangeably. "Multiple" refers to two or more; therefore, in this embodiment, "multiple" can also be understood as "at least two." "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / ", unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship. Furthermore, it should be understood that in the description of this embodiment of the invention, words such as "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or order.

[0027] Traditional resin cleaning devices often suffer from problems such as discontinuous cleaning processes, inconvenient material loading and unloading, and low cleaning fluid circulation efficiency. For example, some devices lack a separate connection structure between the water storage container and the cleaning container, resulting in unstable cleaning fluid supply; the cover design of the cleaning container is unreasonable, affecting the convenient loading of resin; and improper placement of the water outlet and inlet can easily lead to cleaning fluid residue or incomplete cleaning.

[0028] Please see Figures 1-3 This utility model provides a resin cleaning device, which includes: a water storage container 2 connected to a cleaning container via a water injection pipe 15; the cleaning container includes a tank body 1, a cover body, and a stirring device; the cover body is provided with an openable cover plate, and the resin to be cleaned is poured in from the cover plate; the tank body 1 is provided with a discharge port 4 at the bottom, a water inlet connected to the water injection pipe 15 is provided at the bottom of the side wall of the tank body 1, and a water outlet is provided at the top of the side wall, and the cleaned resin is discharged from the discharge port 4.

[0029] In one embodiment, the water storage container 2 is connected to the bottom water inlet on the side wall of the cleaning container 1 via a water injection pipe 15. The water injection pipe 15 can be made of pressure-resistant material, such as stainless steel, to ensure that there is no leakage during the delivery of the cleaning fluid. A cover covers the top of the tank 1 and is provided with an openable cover plate. The resin to be cleaned is poured into the tank 1 through the opening of the cover plate. After the cover plate is closed, a sealed space is formed to prevent the cleaning fluid from splashing out. The bottom of the tank 1 is conical, and a discharge port 4 is provided at the center of the bottom for discharging the cleaned resin. The bottom water inlet on the side wall is connected to the water injection pipe 15, and the cleaning fluid enters the tank 1 from the water inlet. The top water outlet on the side wall is used to discharge the cleaning waste liquid, forming a bottom-up water flow to thoroughly rinse the resin.

[0030] The water supply to the cleaning container is stabilized by connecting the water storage container 2 to the water injection pipe 15. The openable cover on the lid facilitates the rapid addition of resin. The layout of the bottom outlet 4, the bottom water inlet on the side wall, and the top water outlet of the tank 1 forms a "bottom in, top out" cleaning liquid circulation path, ensuring that the resin is fully in contact with the cleaning liquid and facilitating the discharge of waste liquid after cleaning, thereby improving cleaning efficiency and quality.

[0031] In traditional devices, the pressure resistance of the water storage container 2 and the cleaning container may be inconsistent, which may lead to water leakage or container deformation during high-pressure cleaning; the water injection pipeline 15 lacks an automatic control device and requires manual operation of the valve, which affects the degree of automation of the cleaning process.

[0032] In this embodiment of the utility model, the pressure resistance range of the water storage container 2 is the same as that of the cleaning container, and a water injection solenoid valve 16 is provided on the water injection pipeline 15.

[0033] In one embodiment, the water storage container 2 and the cleaning container are made of the same material and have the same wall thickness to ensure that their pressure resistance ranges are consistent. A water injection solenoid valve 16 is connected in series in the water injection pipeline 15, and the input end of the solenoid valve is connected to the control system, such as PLC control. During cleaning, the control system sends a signal to open the solenoid valve, and the cleaning fluid in the water storage container 2 is injected into the tank 1 through the water injection pipeline 15. After cleaning, the solenoid valve is closed to cut off the liquid path.

[0034] By ensuring that the pressure resistance range of the water storage container 2 and the cleaning container are consistent, the system can be made to operate stably under high-pressure cleaning conditions. A water injection solenoid valve 16 is installed on the water injection pipeline 15, which can remotely or automatically control the injection of cleaning fluid through the control system, thereby improving the ease of operation and the level of process automation.

[0035] Traditional cleaning devices lack real-time water quality monitoring interfaces, requiring sampling from inside tank 1 after shutdown. This operation is cumbersome and makes it impossible to monitor water quality in a timely manner during the cleaning process, resulting in difficulty in controlling the cleaning effect and potentially causing over-cleaning or substandard cleaning.

[0036] In this embodiment of the present invention, an artificial water sampling port 3 is provided on the top of the side wall of the tank 1.

[0037] In one embodiment, the sampling port adopts a threaded interface or a quick-connect interface, located at the top of the side wall of the tank 1 and higher than the water outlet. A filter device, such as a filter screen, is installed inside the interface to prevent resin particles from entering the sampling pipeline. During the cleaning process, the sampling port valve is opened, an appropriate amount of cleaning solution is collected with a sampling bottle, the valve is closed, and water quality is tested. The test results are then used to determine whether to continue cleaning or replace the cleaning solution.

[0038] By setting an artificial water sampling port 3 on the top of the side wall of tank 1, the upper cleaning liquid can be extracted at any time during the cleaning process to detect indicators such as impurity content and pH value, and the cleaning progress can be judged in real time, avoiding waste of resources and ensuring controllable cleaning quality.

[0039] Traditional tanks have a fixed inner wall roughness. For resins of different particle sizes, small-particle-size resins may be adsorbed on the rough inner wall and difficult to be discharged, or large-particle-size resins may not collide sufficiently when cleaning on the smooth inner wall, resulting in low cleaning efficiency and high residue rate.

[0040] In this embodiment of the invention, the roughness of the inner wall of the tank 1 is set to correspond to the particle size of the resin to be cleaned.

[0041] The inner wall roughness of tank 1 is specifically designed based on the particle size of the resin to be cleaned. Small-particle-size resin corresponds to lower roughness to reduce adsorption; large-particle-size resin corresponds to higher roughness to enhance collision friction, improve cleaning effect and reduce residue.

[0042] In this embodiment of the utility model, the bottom of the tank 1 is conical, and the discharge port 4 is located at the top of the cone.

[0043] By making the bottom of the tank 1 conical and setting the discharge port 4 at the top of the cone, the resin is automatically gathered to the discharge port 4 by gravity, avoiding residue; the conical structure reduces dead corners, facilitates cleaning and material discharge, and improves discharge efficiency and cleanliness.

[0044] Traditional lids are mostly one-piece designs, which are inconvenient to open, especially for large tanks, requiring multiple people to operate; when the stirring device passes through the lid, the sealing performance is poor, which can easily lead to leakage of cleaning fluid or entry of impurities.

[0045] In this embodiment of the utility model, the cover includes a central support beam 5 and a first cover plate 7 and a second cover plate 8 located on both sides of the central support beam 5. The central support beam 5 is fixedly disposed at the center of the top of the tank 1. The first cover plate 7 and the second cover plate 8 are respectively flipped and connected to the two sides of the central support beam 5. The edges of the central support beam 5, the first cover plate 7 and the second cover plate 8 are matched with the opening of the tank 1. A stirring through hole is provided in the center of the central support beam 5.

[0046] In one embodiment, the support beam 5 is a metal profile, such as an I-beam, which is welded or bolted to the center of the top of the tank 1. A stirring through hole is opened in the center of the beam, and the diameter of the stirring through hole matches the stirring shaft 11. The first and second cover plates 8 are connected to the two sides of the support beam 5 by hinges or latches. The edge of the cover plate is provided with a sealing strip, which fits tightly with the tank opening when closed; when opened, it can be flipped upward and fixed, and can be limited and fixed by buckles, exposing the feeding port.

[0047] The cover adopts a structure of central support beam 5 and two flip-top cover plates. The central support beam 5 is fixed to the top center of the tank 1, providing a support point for the installation of the stirring device. The first and second cover plates 8 can be flipped open independently, which is convenient for feeding from one side or both sides and is flexible in operation. The edge matches the tank opening to ensure a seal, and the stirring through hole is coaxial with the drive shaft to ensure stirring stability.

[0048] In this embodiment of the utility model, the stirring device includes: a driving device 9 connected to a fixed base 10, the fixed base 10 being fixedly disposed at the top center of the central support beam 5, the fixed base 10 having a circular hole 6 at its center, the driving device 9 including a driving shaft vertically disposed towards the interior of the tank 1, the driving shaft being coaxial with the center of the circular hole 6 and the center of the stirring through hole; and a stirrer including a stirring shaft 11 and stirring blades, the stirring shaft 11 passing through the circular hole 6 and the stirring through hole, and being coaxially connected to the driving shaft.

[0049] In one embodiment, the base is a circular metal plate with a circular hole 6 in the center, which is fixed to the top of the support beam 5 by bolts. The center of the circular hole 6 coincides with the center of the stirring through hole. The drive shaft of the drive device 9 passes vertically downward through the circular hole 6 of the base and is coaxially connected to the stirring shaft 11 of the stirrer through a coupling to ensure transmission accuracy. Sealing rings are provided at the connection between the base and the support beam 5 and at the point where the drive shaft passes through the circular hole 6 to prevent cleaning liquid from splashing into the drive device 9.

[0050] The drive unit 9 is fixed to the top center of the central support beam 5 via the fixed base 10. The drive shaft, the round hole 6, and the stirring through hole are highly coaxial, ensuring that the stirring shaft 11 rotates smoothly. The stirrer is coaxially connected to the drive shaft, which reduces vibration, improves the uniformity of stirring, and avoids local accumulation of resin.

[0051] Traditional agitator blades are mostly single-layered or simple structures, with limited agitation range and uneven cleaning of resin between upper and lower layers; unreasonable blade layout can easily create agitation dead zones, resulting in low cleaning efficiency.

[0052] In this embodiment of the present invention, the stirring blade includes a first stirring part 12 disposed at the bottom of the stirring shaft 11, a second stirring part 13 disposed at the middle of the stirring shaft 11, and a third stirring part 14 disposed at the upper part of the stirring shaft 11. The first stirring part 12, the second stirring part 13 and the third stirring part 14 are staggered in vertical projection.

[0053] In this embodiment of the present invention, the first stirring part 12, the second stirring part 13 and the third stirring part 14 are all rectangular frames with equal length and width; a horizontal crossbar is provided at the horizontal center of the second stirring part 13; and cross crossbars are provided at the horizontal center and vertical center of the third stirring part 14.

[0054] In this embodiment of the present invention, the first stirring part 12, the second stirring part 13 and the third stirring part 14 are each composed of two stirring frames symmetrically arranged with the stirring shaft 11 as the center.

[0055] In one embodiment, the first stirring section 12 consists of two symmetrical rectangular frames and is vertically mounted to the bottom of the stirring shaft 11 to agitate the resin deposited at the bottom. The second stirring section 13 has a horizontal crossbar at its horizontal center to enhance the stirring intensity in the central region. The third stirring section 14 has intersecting crossbars at its horizontal and vertical centers, forming a "cross" structure, which can break up the upper foam and increase surface disturbance. The first stirring section 12, the second stirring section 13, and the third stirring section 14 are arranged sequentially at intervals in the vertical direction, and the three sets of stirring sections are staggered in their vertical projection to ensure that the stirring trajectory covers the interior of the tank 1.

[0056] By dividing the stirring blades into first, second, and third stirring sections 14, the vertical projections of the three stirring sections are staggered, so that they cover the entire height range of the tank 1 and avoid dead corners; different stirring sections are equipped with horizontal bars or symmetrical stirring frames. The first stirring section 12 enhances the agitation of the resin at the bottom, the horizontal bars of the second stirring section 13 improve the mixing effect in the middle, and the cross bars of the third stirring section 14 break up foam or clumps, so as to achieve uniform cleaning of the entire tank.
