Description

Technical Field

[0001] This utility model relates to the field of storage device technology, and more specifically, to a storage device for epoxy resin production. Background Technology

[0002] Epoxy resin is a widely used thermosetting polymer, favored for its excellent mechanical properties, chemical resistance, good adhesion, and electrical insulation properties. It is typically prepared by reacting epoxy group compounds (such as bisphenol A type epoxy resin) with a curing agent. Epoxy resins can be used in a variety of fields, including but not limited to coatings, adhesives, composite materials, electronic packaging, and civil engineering.

[0003] Because epoxy resin is a thermosetting polymer, it needs to be stored in a sealed container. This container typically contains a stirring mechanism to prevent curing. However, epoxy resin easily adheres to the inner wall of the container, and if not cleaned promptly, a thick cured layer will form over time. Current technology only allows for either a stirring mechanism or a wall-scraping mechanism within the sealed container; it cannot simultaneously provide both functions. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a storage device for epoxy resin production that can both stir and scrape the wall without affecting each other.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A storage device for epoxy resin production includes a tank and further includes:

[0007] A rotating shaft is vertically rotatably mounted inside the tank.

[0008] A stirring arm is disposed on the outer wall of the rotating shaft and multiple such arms are arranged around the axial direction of the rotating shaft.

[0009] A stirring drive assembly is disposed outside the tank body, and the output end of the stirring drive assembly is connected to a rotating shaft to drive the rotating shaft to rotate.

[0010] A wall scraper is movably disposed at one end of the agitator arm away from the rotating shaft, and is used to scrape off the epoxy resin on the inner wall of the tank.

[0011] A wall scraping drive assembly is disposed on the rotating shaft or the tank body. The power output end of the wall scraping drive assembly is connected to the wall scraping component, which is used to drive the wall scraping component to move against the inner wall of the tank body and retract to a distance from the inner wall of the tank body.

[0012] Preferably, the storage device for epoxy resin production further includes a first rotating fixing seat disposed on the top of the tank and a second rotating fixing seat disposed inside the tank and located below the first rotating fixing seat, with both ends of the rotating shaft rotatably mounted between the first rotating fixing seat and the second rotating fixing seat.

[0013] Preferably, the stirring arm has a guide hole, and the wall scraper is provided with a guide rod that guides and cooperates with the guide hole; a stop block is provided at one end of the guide hole near the rotating shaft, and a spring is connected between the stop block and the guide rod. The spring is used to pull the wall scraper back to separate it from the inside of the tank.

[0014] Preferably, the shaft has a central hole; a push rod is installed at one end of the guide rod near the shaft, which movably passes through the abutment and the shaft into the central hole; the spring is sleeved on the push rod, and the power output end of the scraping drive assembly acts on the push rod.

[0015] Preferably, the scraping drive assembly includes a movable shaft embedded in the central hole, and a plurality of clearance grooves are provided on the outer wall of the movable shaft corresponding to a plurality of push rods; it also includes a downward drive component disposed on the top of the tank, the power output end of the downward drive component being connected to the movable shaft, for driving the movable shaft to move downward to push the push rods outward, thereby causing the scraping component to abut against the inner wall of the tank.

[0016] Preferably, the end of the push rod near the rotating shaft is arc-shaped, and the upper part of the clearance groove is inclined upward.

[0017] Preferably, the side of the scraper that contacts the tank body and the side that rotates along the axis are both pointed surfaces.

[0018] Preferably, the top and bottom of the tank are respectively provided with a feed inlet and a discharge outlet.

[0019] Compared with the prior art, the advantages of this utility model are as follows:

[0020] When wall scraping of the tank's inner wall is not required, the wall scraping drive assembly can separate the wall scraper from the tank's inner wall. At this time, the stirring drive assembly can drive the rotating shaft to rotate the stirring arm to prevent the epoxy resin inside the tank from curing. When wall scraping is required, the wall scraping drive assembly can drive the wall scraper to press against the tank's inner wall. At this time, the stirring drive assembly can drive the stirring arm to drive the wall scraper to scrape the tank's inner wall. In this way, wall scraping and stirring are combined, allowing both functions to be used simultaneously. Attached Figure Description

Detailed Implementation

[0028] 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.

[0029] refer to Figure 1-2 An epoxy resin production storage device includes a tank body 1, and further includes: a rotating shaft 2, vertically rotatably disposed inside the tank body 1; a stirring arm 3, disposed on the outer wall of the rotating shaft 2 and arranged in a plurality of such arms around the axial direction of the rotating shaft 2; a stirring drive assembly 4, disposed outside the tank body 1, the output end of the stirring drive assembly 4 being connected to the rotating shaft 2 for driving the rotating shaft 2 to rotate; a wall scraper 5, movably disposed at the end of the stirring arm 3 away from the rotating shaft 2 for scraping epoxy resin on the inner wall of the tank body 1; and a wall scraper drive assembly 6, disposed on the rotating shaft 2 or the tank body 1, the power output end of the wall scraper drive assembly 6 being connected to the wall scraper 5 for driving the wall scraper 5 to move against the inner wall of the tank body 1 and retract to a distance from the inner wall of the tank body 1.

[0030] Understandably, tank 1 has an internal cavity and functions to store epoxy resin. The vertically rotatable rotating shaft 2 can be installed at the top and / or bottom of tank 1 using a bearing or shaft-hole fit structure. The stirring drive assembly 4 can be directly connected to the rotating shaft 2 by a motor, or it can be connected by a transmission chain or belt, but is not limited to these methods. The stirring wall is a component used to stir the epoxy resin; for example, it can be a straight or bent rod structure, but is not limited to these methods. The scraper 5 can be a straight plate structure or an arc-shaped plate structure adapted to the curvature of the inner wall of tank 1, but is not limited to these methods. The scraper drive assembly 6 can be driven by an electric push rod 53 or a threaded screw, and can be located inside or outside the stirring arm 3 or rotating shaft 2. The movable scraper 5 can be a telescopic structure with a shaft-hole fit, a sliding fit structure with a guide rail, or it can be moved directly by the linear drive of the scraper drive assembly 6.

[0031] With this configuration, when scraping the inner wall of the tank 1 is not required, the scraping drive assembly 6 can drive the scraping component 5 to separate from the inner wall of the tank 1. At this time, the stirring drive assembly 4 can drive the rotating shaft 2 to rotate the stirring arm 3 to prevent the epoxy resin in the tank 1 from curing. When scraping is required, the scraping drive assembly 6 can drive the scraping component 5 to press against the inner wall of the tank 1. At this time, the stirring drive assembly 4 can drive the stirring arm 3 to drive the scraping component 5 to scrape the inner wall of the tank 1.

[0032] In some embodiments, reference Figure 2 The epoxy resin production storage device further includes a first rotating fixing seat 7 disposed on the top of the tank 1, and a second rotating fixing seat 8 disposed inside the tank 1 and located below the first rotating fixing seat 7. The two ends of the rotating shaft 2 are rotatably mounted between the first rotating fixing seat 7 and the second rotating fixing seat 8. Here, the first rotating fixing seat 7 can be directly disposed on the top of the tank 1, while the second rotating fixing seat 8 can be disposed inside the tank 1 through a connecting rod or other structure, thereby positioning the two ends of the rotating shaft 2 and improving the stability of stirring.

[0033] In some embodiments, reference Figure 2-4, The stirring arm 3 has a guide hole 31, and the scraper 5 is provided with a guide rod 51 that guides and cooperates with the guide hole 31. A stop block 32 is provided at one end of the guide hole 31 near the rotating shaft 2. A spring 52 is connected between the stop block 32 and the guide rod 51. The spring 52 is used to pull the scraper 5 back to separate it from the inside of the tank 1. Here, the cooperation between the guide rod 51 and the guide hole 31 not only realizes the telescopic movement of the scraper 5, but also provides sufficient resistance to the guide rod 51 from the epoxy resin during the stirring process. After scraping is no longer needed, the scraper drive assembly 6 withdraws its output force, and the scraper 5 can be automatically separated from the inside of the tank 1 by the pull of the spring 52.

[0034] In some embodiments, the shaft 2 has a central hole 21 at its axis; a push rod 53 is mounted on one end of the guide rod 51 near the shaft 2, which movably passes through the abutment 32 and the shaft 2 into the central hole 21; a spring 52 is sleeved on the push rod 53, and the power output end of the scraping drive assembly 6 acts on the push rod 53. Thus, the output end of the scraping drive assembly 6 can extend into the central hole 21, thereby acting on the push rod 53 to move the scraping component 5. Further, the scraping drive assembly 6 includes a moving shaft 61 embedded in the central hole 21, with several clearance grooves 611 on the outer wall of the moving shaft 61 corresponding to several push rods 53; it also includes a downward driving member 62 disposed on the top of the tank 1, the power output end of which is rotatably connected to the moving shaft 61, used to drive the moving shaft 61 downward to push the push rod 53 outward, thereby causing the scraping component 5 to abut against the inner wall of the tank 1. The downward pressure drive 62 can be a cylinder or an electric push rod 53. Since the rotating shaft 2 drives the moving shaft 61 to rotate during the stirring process, the moving shaft 61 and the power output end of the downward pressure drive 62 cannot be directly connected; they can be spaced apart or connected by bearings. In its natural state, the push rod 53 is embedded in the large clearance groove 611, and the scraper 5 is also separated from the inner wall of the tank 1. When the downward pressure drive 62 presses down, refer to... Figure 3 The moving shaft 61 moves downward, pushing the push rod 53 outward, thereby causing the scraper 5 to abut against the inner wall of the tank 1. Similarly, during resetting, refer to... Figure 4 When the downward driving component 62 moves upward, the moving shaft 61 can be moved upward by the downward driving component 62, or it can be due to the spring 52 pulling back the push rod 53 in conjunction with the clearance groove 611 to push the moving shaft 61 upward. At this time, the push rod 53 is re-embedded in the clearance groove 611, and the wall scraper 5 separates from the inner wall of the tank 1.

[0035] Furthermore, the end of the push rod 53 near the rotating shaft 2 is arc-shaped, and the upper part of the clearance groove 611 is inclined upwards. Thus, during the downward movement of the moving shaft 61, the inclined part of the clearance groove 611 presses against the arc-shaped end of the push rod 53, guiding the push rod 53 outwards, making the movement of the wall scraper 5 smoother.

[0036] In some embodiments, reference Figure 2 and Figure 5 The scraper 5 has a pointed surface on both the side that contacts the tank 1 and the side that rotates along the axis 2. This allows the scraper 5 to effectively remove epoxy resin from the inner wall of the tank 1. During stirring, the pointed surface also helps reduce resistance.

[0037] In some embodiments, reference Figure 1-2 The tank body 1 is provided with an inlet 11 and an outlet 12 at its top and bottom, respectively. The inlet 11 is used to input epoxy resin, and the outlet 12 is used to output epoxy resin. Pipes and valves can also be installed at the inlet 11 and outlet 12 to facilitate the input and output operations.

[0038] The above description is merely a preferred embodiment of this utility model; however, 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 technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
